You're kinda making it clear your projecting your own family issues onto op as my original comment to you. I have a psycho sister too, thing is, there's a difference between differences in thought and being a literal fucking psycho, psycho is sending is shattering the family at the drop of the hat because you feel slighted, thinking Elon is the coolest dude ever (he isn't) isn't the same level, things aren't black and white.
OP, unless you're in therapy and Shezzgrad is your licensed professional help, then ignore their advice.
When I said it originally I was being a dick, but I think you may want to genuinely consider therapy, family traumas can be everlasting and can really kick in later on in adulthood, your sister experience sounds similar to mine
Well said, in my personal opinion we should stick close to family but there are lines, and each person's lines are different, but I feel generally that line should be for their actions and not their ideas or thoughts. Being a trump supporter Vs a Jan 6 rioter or a proud boy are different levels to me. We should try to change our families mind to an extent, if they can't or won't change or if you're not a great debater. Honestly unless your family hurts others, I can keep it together.
