Kids don't respond to mockery they way we did when I was younger. At least not to mockery that is too overt. Yeah, you can joke about his behavior but it could likely backfire. Instead, try to teach the kid to act in a manly way. Give him masculine role models to emulate instead of allowing him to form his opinion of what it means to be a man by watching 'influencers' online.

Suggest he learn a trade and teach him skills that he'll need in life. Basic carpentry and repairs, like drywall and framing. Painting. Electrical. Plumbing. Work on projects that will build character but also teach skills. Install a fence. Fix a sidewalk. Swap out that crappy old mailbox for a new one. Have him help you mow the lawn, and have him help the elderly couple down the street with their lawn.

Basically, be the man you want him to grow up to be.

Encourage spending time outdoors , camping ( real camping , not RVs ) , hunting , fishing , hiking. Join a well qualified MMA , Jujitsu, Muay Thai or Wrestling school .

As best you can , share these truths. Push yourself , do shit you don't like doing , just because it needs doing . Be hard on yourself , and be charitable with others.

Consider yourself lightly , and the World deeply. Live without regret , learn from past missteps , but don't dwell on them. The world owes you nothing , just because you exist

Mock him relentlessly until he hates your guts, then act really gay so he does the opposite.

Be an example for young males to act like men. Be sober, strong and healthy. Be courteous, kind and compassionate. If you are faith filled Christian, practice your faith. Be a good father to your sons and daughters.

Talk about history and the men of the past that made differences in the world as men. Explain to them the purpose of manhood: to make babies; to protect and provide for his family.

Ignore man. Seek God.

Educate him to avoid all of the phyto- and xeno-estrogens in the food supply.

Also, educate him on how, for the last 30 years or so, boys and young males have been been socialized / mis-educated to act as dysfunctional girls through the ADD scamdemic and the jew-inspired "emotional intelligence" farce.

Until his first instinct is to think (masculine) rather than feel (feminine), the problem will remain.

Make fun of gays but don’t be too mean. If you go overboard, in his head he’ll gain that victim status they all want. I agree take the social media away too. Look into what tv shows he watches and don’t allow ones with mention of LGBT. Look at the teachers, friends and other people in his life. If someone’s been acting fruity around him he could be picking up their body language whether he thinks he’s gay or not. Maybe the straight men in his life are unkempt, fat, slobs and he’s listening to media influence tell him the only way to be ‘good’ is to be a fag. I remember seeing that bs a lot when I was younger. “All the cute ones are gay,” we’d say. Work out, eat right, have a good work ethic. Seem more put together than the other side, otherwise he won’t listen. That was my issue when I was younger. The adults telling me groomers were bad were all fat and stupid in most aspects of their life. One of the few things they did right was warn me about media and how it brainwashes, and that if gays were allowed to be married it’d end up a slippery slope till the fags go after children too. These same people who were right about that couldn’t take care of themselves so why would I listen to them? The whole point on looking down on the fags us they’re evil, dysfunctional, and unnatural. Be the opposite of that and the kids will eventually notice the difference.

Take a shit on the floor and ask if thats what he wants to stick his dick into

Immediately take away ALL electronics. No social media, no television, so tablets, no phones. Off possible put the kids in homeschool. Doing all this will prevent further brainwashing. Peer pressure is more powerful than we give it credit for. Especially with young men who haven't found their confidence or voice yet.

A friend of mine has a son and he's acting really gay, should we just mock this behavior?

How is he acting gay exactly? You are an adult, you should provide him guidance, leave mocking to his peers.

Also what masculine traits should we imprint on these boys and how?

Get them to read books or watch documentaries (non kiked, think Asha Logos) that will show teach them what great men through out history have achieved, give them sense of pride to their race and nation. Right now all they see is blackpill and faggotry from all sources all around.

Next would be to encourage them to go to nature, hiking, exploring, camping, traveling anywhere - but on their own given they are old enough, so no adults holding their hands. Camping alone in the wilderness with nothing but a knife or/and a gun + what you managed to carry in you backpack will turn any boy into a man.

Next, physically and outdoor activity, competitive sports, combatives and fighting skills and range time. Gym when they are ready, bodyweight training until then. You don't need much to start with these, especially now with good sunny weather coming in.

Next, any skills that will teach them self sustainability and self reliance, cooking, grilling, car mechanics (buy them an old junk car or motorcycle as a project to fix it up - excellent for summer time), around the house maintenance work, growing food, stuff like that.

If any of them ever complain about the sad state of "clownworld" tell them this "Do you have both arms? Yes! Do you have both leg? Yes! Do you have a brain in your head? Yes! Do you have a whole life of almost an entire fucking century ahead of you? Yes! Now start thinking and planning of how you will shape this world to not be the clownworld you hate so much."

And last but not least, guide by an example. If all adult men in their community are all fatass weak losers sitting around and chugging bud light, only rare kids will be able to rise above that if not given a proper environment and guidance to grow.

If you need me to elaborate or give you more info/plans/ideas on how to do any of these things feel free to ask.
