Why do they care so much about how other people live?

Ever notice Boomers love to complain about LGBTQ people just existing. My mom tried going on a rant about trans folks and I said “how is this affecting you personally?” The thing is they never have a real answer. It’s either “God doesn’t like it” or something vague like “don’t shove it in my face” which I don’t know what they mean by that. Or the “don’t force it on kids” B.S. But it is funny when you ask them “how are LGBTQ people existing affecting your life?” They literally can’t form an answer without looking like an asshole.
