Certain people are stubborn. Just try not to loose (whoops) I mean lose your temper when dealing with them. It's frustrating, but as long as you understand that you trust your opinion, you'll be fine. If they're not willing to see things from your point of view then they have no right to get upset when people don't accept their opinion.

Here's some suggestions, cho[o]se all or none or a combination:
Tell yourself you're a genius (If you aren't, who cares, if you are, ha!)
Adopt a sense of arrogance, of dismissiveness
Do push ups or weights or get into an intense League of Legends match while they get in your face about it. "Hold up, let me just take the damages and I'll address your points after..."
Change the subject with wit ("If you can't choose to lose, then you lose to choose" And they're like, "the fuck?" And then you're like, "Whatever dude, all I know is that I have bars" and if they confront you on that: "You're not a rapper!" You pull out a Snickers and say correctively, "Chocolate bars. And I have a wrapper." They can't argue with facts in front of them. Keep the trolling if you can, what are they gonna do, punch you in the face? Maybe you need that. You've ever seen Fight Club?)

Unfortunately that is just the way some people will be. Just keep their behavior and habits in the back of your mind so you know what to avoid or expect. It's surprising how these things come out when you change or question beliefs.

I used to be able to talk to my father about anything and wouldn't as much with my mother. After deconversion... It flipped. I can't talk to my father or he flips out. My mother is totally open and likes to listen.

One of my brothers is like that. We just don't talk to him all that much.

I came out as gay in the mid 1980's and most of the other gay people I met had issues with family. They and I, simply sought out good honest friends, who could give the support our families refused to give. In a sense, creating our own "families."

My criteria for friends was based primarily on how honest they were, the more honest the more open I'd be to getting close to them.

I accept their ignorance and try to to illustrate though my beliefs differ, they are every bit as valid. This tends to fall on deaf ears.

It sounds as though you may need different people to talk to...
