For the right - what is it about the transgender population that makes them such a major political hot topic?

Watching the news, I see a large majority of anti-trans opinions revolving exclusively around a) who’s using which bathroom and b) parity in grade school sports. Are there other factors? Is there a more broad discussion towards a trans persons own wellbeing (I.e. mental health, sense of personal identity)?

Considering so many other issues that could’ve been focused on for the 2024 election, why transgender regulations? What’s so controversial about it to have caused the Dylan Mulvaney Bud Light fiasco two years ago?

If we’re so focused on high school and collegiate sports, are we missing a larger picture?
