Pressure politicians into making laws that stops them from going into our bathrooms. Start small if you have to, get bans on them going into the wrong bathroom at schools first. Then government buildings. Or if most in the state seem to agree go for having the whole ban on it everywhere. There are only 2 states that have laws against them going into the wrong bathroom anywhere iirc. That number can and will grow as people get more and more fed up with the troon bs. As for stopping it yourself at a particular place, like if you own a business or something. You could put XX, XY on the doors and then have the male and female signage to go with it in case some moron doesn't know what chromosomes are (low IQ or a child). A better, less confusing thing might be to have a sign next to the bathrooms that says "For the safety of others please use the restroom that corresponds with your biological sex." Make it polite instead of rude. I don't want to look at images of genitals even though I 100% agree trans shouldn't be allowed in the wrong bathroom. Lol. You can be as proper about it as you want, you'll still trigger the troons.
