I think that first you need to be safe. You can’t help anyone if you get hurt.

If you are safe and you are a men, you can help by setting example. I mean, usually, the really strong and confident men won’t care about doing things that are “coded” as femenine because they have nothing to prove. The more men that do something, the more normal it becomes. Now men wear bags and no one consider it “gay”. Same with emotions.

And if you are a woman, you can say “I like when men who do that”. They might try to said is not true, or contradict you, but you can repeat it. And since you are talking about *your* preferences and what *you* (not others) like, there is very little they can do to contradict that. The more women who say it, the more difficult it would be to paint it as “an exception”.

Small things change people’s perception.

As for the people in pain, well, of they are aggressive, stand up and left. If they shout, left. But listen when they behave calmly. And suggest things that might help them. For example, practicing a team sport might be an accepted way to bound with others. Sports if done with others are a good and healthy way to meet people. Or joining a class for a hobby. Anything that force you to do something with others and collaborate.

But at the end of the day, it is a work they have to do themselves.
