It helps to be personable first, then when they are relaxed you slam down some red pills, unapologetically. Learn to be humorous about it, and look people in the eye, remember their name, be considered honorable. No one cares what an unwashed asshole has to say. Be upstanding, even if you are poor. But at the end of the day, understanding the truth is way more important than "social credit". Through the vast majority of European development we lived caring little for such things. Social adherence is petty, even when society is proper. Simply be a good example, and others will adopt your ways and be more open to what you have to say, even if it shocks them.
