I've joined a political discussion telegram group and I'm evangelising Bitcoin to between 100-200 people.
It always surprises me how little a lot of people really know about Bitcoin, most are stuck in the FUD headlines from 5+ years ago.
I really believe one of the best things anyone can do to help Bitcoins cause, is just to talk about it openly with your full conviction without holding back.
No need to push, or go out of your way to talk about it, but if the conversation relates and you would naturally speak about it with other Bitcoiners, then speak your truth.
No need to defend or fight for it even.
I find simply speaking your truth and then inviting people towards some deeper research (providing some links), before leaving in peace and respect, is a powerful way to influence others.
