Transgender athletes- why do they care SO much?

So, the number of transgender athletes competing in sports is tiny, a relative handful. Why, then, is this the topic at least once a week of raging, angry FoxBrained Facebook posts? Is it because of Fox continually airing segments on it? I’d have to think most people do not particularly care, or if they do care, it’s a mild opinion one way or the other. (I don’t really have a problem with it, but maybe the opinions of the athletes competing in these respective sports matters more). If I had to rank the list of issues I’m concerned about these days, transgender athletes at any level of competition would be way, wayyyy down the list. The outage Is not proportional to the amount of people it actually affects, is my point.
