I have not seen any indication that Rowling, Musk, or Adams assert that trans people are categorically a "major threat". That said, these folks do view trans people as a "major threat" to those athletes who compete in the category that once was exclusive to humans distinguished by having XX chromosomes. They believe, and rightly so in my opinion, that this athletic competition category should remain exclusive to those humans scientifically established (usually pretty obvious at birth) to have XX chromosomes.

It is entirely possible your heart is in the right place, but this specific comment gives it away that you haven't actually looked at this issue too closely. There are "scientifically established" reasons why this issue is a lot more complicated than the anti-trans folks always make it out to be, even if we completely ignore the existence of trans people. Look up Swyer Syndrome[1] for example.
The obvious indication is that they’re putting a huge amount of time and money into this issue. If they don’t think it’s a major threat then what are they even doing?
