I’ve had this exact same epiphany after having arguments with my parents about politics… Like, “You made me this way!”
It’s very sad. I’m fortunate that it was the opposite for me. Born into a hyper-conservative Catholic family, then when 3 out of 4 of their children wound up LGBTQ, they realized that God might have been telling them something. They’re extremely and refreshingly Christ-like, and total allies. They treat my same-sex fiancé as their full-blown in-law.
I wouldn’t call that a contrast honestly. Sounds like a very similar attitude.
One would think the choice would be obvious: Either accept your children for who they are, or accept some right-wing bullcrap and only get to talk with the one kid you didn’t shun from your life.
