It isn’t a pronoun. It’s a Latin prefix, I don’t see it as awful but I’ll respect your feelings about it and not use it.
I know recently opinions have shifted on it because Elon Musk declared it a slur (shame nobody who matters gives a flying **** what he thinks) and it has begun to be seen as divisive within the community, because it suggests that LGB people don’t struggle with gender identity, which is of course untrue. However, it is still widely used in academia and the scientific community because it stands in contrast to the prefix trans-, which means “the other side”, which I can see as divisive but also kind of ironic when said by certain people I know on social media, given their views on trans people.
It's more about facts than feelings, I thought you'd try to latch on to the grammar aspect, but your attempt at a lesson in English is simply a diversion away from the issue, as the use of pronouns is an absolute mess, and has no meaningful link to scientific facts anyway.
It's no good claiming to respect the fact that people don't like it and then trying to justify it's use, or trying to claim some nonsense about it being down to Musk. You mentioning that indicates you know that people find it objectionable, yet you still chose to use it. The blame sits squarely with the hypocrites who try to sneak it in in the hope it becomes legitimate,
It isn't used much in credible scientific circles, as it's pretty much a term created by a movement started by people with extremely dubious sexual preferences designed to legitimise their claims. Until relatively recently, gender was more a term for inanimate objects.
As I said earlier, I don't care how others choose to live, and I actually like to see people being individuals and characters and being free to choose, but as also mentioned, I'm not alone in believing that the current trend is a fashion doing more harm than good, as it's been hijacked by people with other agendas. That is a view shared by people I know that are long term cross dressers and gays who say it's making their life harder, and the push back is not usually from straight people.
I mentioned earlier the fights I saw in town, and they were alphabet people disagreeing with other alphabet peoples views.
If they can't understand the gay b c's, then it's understandable that others don't either, but at least the straight people seem to be far more tolerant.
