There is a legitimate argument in favor of prohibiting some trans females from participating in women’s sports. This issue was already being regulated by international and domestic sports organizations, however, and in the big picture, it is a minnow. Anyone who was inspired to vote for the GOP on that basis was an utter fool.
There is a marginal argument for the state to limit the ability of minors to transition in light of the coercion that was being applied to doctors by trans activists. This was also a very minor issue, however. Decisions about transitioning should be made by patients, parents, and physicians without any coercion, either by activists or the government.
That said, the most important thing to remember about trans people is that they are people. Regardless of how annoying the activists are, there is no moral basis for dehumanizing, oppressing, and discriminating against them, which is precisely what the current government is doing today.
