We are trying to let people be who they are as long as they don’t hurt anyone. Unfortunately the subset of the population attacking LGBTQ, abortions, and supporting continued prevalence of firearms are actively and deliberately supporting harm.
Kids don’t give a shit if someone’s gay unless someone teaches them to have that hatred.
I was recently at an event with enough, drag, trans, and gender fluid people that the "he/she/they" thing became a legitimate thing of note.
My young daughter was completely unfazed by it.
Children are often a mirror showing us how we appear to the world. It can be unnerving seeing your negative characteristics reflected back at you. However, if you're caring and accepting, they will pick that up and express it themselves.
There are gay people. You just have to get used to that idea. There have always been gay people and there will always be gay people. There have always been trans people and there will always be trans people. In fact, there are more LGBTQ... people out there than there are natural blondes, natural redheads, and people with blue eyes. The existance of gay and trans and every other thing is normal (if you believe that being blonde, red haired, or blue eyed is normal.) So, stop teaching your children to fear, to hate, and to hate themselves if they aren't what you've told them is ok and you won't have this problem.
