ObliviousEnlightenment
You could ask that question, but the answer doesnt matter politically. Women, cis and trans, are on the same side in that if the genocide of the latter is plausible, the former is already pretty hard done by. A worsening of one position necessarily accompanies the other. Gaza does not work like this. Republicans are obviously the worse choice there too. You can argue about red lines and such, but thats not how realpolitik works. We get two options, nothing more or less, zero alternatives. The consensus necessary to change this is not possible in the current political climate. Denying support to the lesser evil on the basis of said evil when their opponent will do that same evil but more is not logical.
Tangentially relatee, there are those who sacrifice trans women for the sake of cis women. We call them terfs, and they’ve largely backed rightwing parties
