It's because they don't actually care about any of these groups. Not as the groups that they actually are, they care only about the idealised representation that they feel must be driven forwards - and is only achievable in the world they wish to impose upon every single other person, that vast mass of people who haven't educated themselves into slavish allegiance to their own ideology, which of course, in it's own idealised representation, will result in the elimination of hunger and want across the world! It's quite a shame that us peons in the real world will be stuck with the real-world implementation of this ideology which has, in every attempt, resulted in piles of bodies too numerous to count and a devastated country once the ideological shackles are thrown off.

If they actually cared they'd stop and listen to trans people that disagree with them, rather than either ignoring them, deplatforming them (which is an attempt to force you to ignore them, whether you wanted to or not) or vilifying them and trying to drive them out of the public square.
