usually the participants at FWS board are smart enough to not throw every prejudice together and stir.
I agree with you partially in that the connection between men and school shooters is often a sense of entitlement and feeling misunderstood (and probably not revered enough), but so is the connection between men and a subgroup of TW (entitlement: mansplaining femaleness to them, being "a better woman" than a woman...).
The fact that the trans-state is discussed is probably mostly as a reaction to the "we just want to live our lives" statements that are posted all the time, as this is the complete opposite: aggression and drama.
The other reason why it's discussed was mentioned by me and others, too: there could be psychological problems lurking behind body dysmorphia and feelings of the "wrong body", which could be part of the real reason. It is important that this is at least investigated and not swept under the carpet. There were several trans mass shooters in recent years and it is relevant for prevention to find out where the connections are.
The easiest way to disconnect the shooters from their trans status is to search and find an underlying (psychological / psychriatic reason that so far has been overlooked, not to close your eyes. I rather think so far we often only see the surface as it's so discouraged to look further.
