It's weird, in my family the black sheep are the ultra conservatives whereas everyone else leans from Liberal (at the most Right Leaning) to "Let's burn down a mansion and eat the first non-servant who runs out alive!"
I was kinda glad that the uncle who was "Always trying to be my friend, always hip and cool and with it despite actually being none of those things and instead coming off as an annoying asshole." basically stopped talking to me or even acknowledging my existence beyond telling his son/my cousin that I was possessed by Demons that made me cut off my dick and that's why they gotta get the Mexicans outta America before they teach Evolution to white children (Barely an exaggeration), and his son/my cousin was smart enough to basically say "My Dad says you're evil, but I'm actually going to be somewhat nice although still an annoying little bible thumping shit, because if you're evil you have all the Satanic Video Games in VR!"
and I said "Well at least you have some level of thinking for yourself, here's my Occulus (I'm not calling it a Meta), go nuts."
Lately only my Aunt has been coming to Thanksgiving Dinners while the uncle and cousin have been staying at home, apparently she's starting to get sick of their Right Wing Christofascist Bullshit.
For the record, she's Anti-LGBT, Pro-Trump, and believes they eat dogs in Ohio, she's just sane by comparison to her husband and son.
Like it's the difference between "Trump's racist, but at least he's not a Democrat" Vs. "Trump is literally the Messiah, We're gonna send the infidels to Christ for Judgement!", Far Right Vs. QAnon Shit
We're very civil about it in the hopes that she and hopefully the son too, can break away from her husband's nonsense.
For the record: My aunt is the one related by blood, not the uncle.
I will say this, I hate Reddit Atheists; the kind that jump on your case for shouting "Oh God!" when you're scared and worship the Sacred Texts of St. Hitchens. But if every religious person I ever met was like my uncle and his son, I'd totally get why Reddit Atheists are the way they are...
Last time the kid came to Thanksgiving, he was talking to my sister about Jurassic Park... Then during dinner when I was just making conversation, (Everyone eats at the same table, we don't have a separate "Kid's Table" sides they were in their late teens anyway) I made the mistake of treating dinosaurs as if they were real and not an elaborate creation of Hollywood.
He kept chanting "The Big Bang is a Faerie Tale, not a theory!" until I "apologized to Jesus for my blasphemy."
They actually had to take him out of public school and put him in a private Fundie school because he kept failing his classes due to trying to claim most of History and Science didn't actually exist on his assignments.
I'm deeply worried; one day that guy (He's an adult now) is going to leave the bubble created for him by his Church and his father, and he will not be even slightly equipped to begin to comprehended the world outside.
