In my sarcastic stupid imitation of the average Left poster I can answer your question.
Because, shut up!
And this is really an answer worth pondering, because it shows the repression of free ideas and speech that is necessary to the cultish Left. All they need to go total Fascist is a leader in the open with a face to attach the ideas to, but instead they are guided by shadows in the back rooms.
Forward, goose steppers !
Corrected that for you.
Normal left poster would have answered: one fight being important doesn't mean you have to only chose this one. I know it seems incredible to the like of you who regularly explain that it must be "natives first" but you can ACTUALLY solve more than one problem at once.
Yeah I know, it's incredible. Multitasking at its best.
PS. Funny how you try to put "left" as the "we don't accept any other idea than ours being voiced about" when you and your kinds are the first one to use rethoric to get rid of ideas not following your dogma.
