Teaching acceptance of other lifestyles is a good thing in general. However, there are some irritating side effects for sure. My oldest daughter is a freshman in high school and there are a ridiculous amount of kids who think they can just claim "I'm a guy" (if they are a girl) and that they want to be referred to by male pronouns and called by a different, male first name. She has a couple of friends that are like that and sometimes gets frustrated that I do not use the correct name/pronouns when talking about these girls. I decided to deal with it this way...I asked her, what do their parents call them? In both cases of her friends, the answer has been "he hasn't told them yet, but he is going to". My answer is simply, I am going to refer to these girls as girls and by their given name until their parents do otherwise. Simple as that.
The thing is, both of these girls are queer, I don't doubt that at all. Even at 14/15 I'm pretty sure they both know. And one of them is probably going to at least be a masculine lesbian. But this whole gender-fluid/"I indentify as" thing is little more than a BS attention-grab in the large majority of cases, IMO. They announce it on their Instagram and tell everyone at school and an instant outpouring of "You are so brave" and "I support you" follows.
It is pretty stupid. I have spoken to my daughter about it many times. The percentage of kids who actually, truly identify as the opposite gender is way, way lower than the percentage of kids who are currently claiming it. If someone struggles with it throughout their teens and decides in their early 20s that this is who they are, fine. But it is just so easy for these 14 & 15 year old kids to just say it (to their peers and not their parents) for the attention that it will bring. I would imagine it might be really insulting to people who legitimately deal with with this identity crisis.
Anyway, this type of thing is happening quite a lot. It is probably not quite as widespread as it seems to me right now because my daughter goes to a fine arts academy and you are naturally going to have way more gay kids in the theater, art, music, et al, programs. But it would be a lot easier for me to take seriously if they would just be gay instead of claiming that they "identify" as the opposite sex, because I think it is bullshit in most of the cases I have seen lately.
