I am going to err on the side of positivity and say that it isn’t so rare. At least, not anymore and when it comes to LGBTQ+. All parents fuck up because nobody knows what the fuck they are doing, but the key is to mot let your hang-ups injure your child. I think a lot of parents have been taking on that challenge for some time now.
I haven’t heard of experiences this positive before. But I think generally most parents will try to be helpful or just be confused.
It is definitely a lot easier than it used to be, and the horror stories tend to be the attention grabbing ones, so are more often seen. I think we’ll see a lot more acceptance for the new generation of teens and young adults discovering themselves now it’s genx/millennials raising kids rather than boomers/genx.
