I've found it helps to talk to other Radfem/GC people, or at least people who are willing to question TRA dogma and consider other perspectives. Pretty much all my close friends are open to discussing it and tend to agree with a lot of what I say. Politically conservative people are often quite open minded to gendercritical ideas, though they are often coming from a more religious point of view. The only ones I don't really talk to much about it are those who identify as trans, or who have trans partners and have very strong feelings about it (most of those are not close friends, though).
