When goals align I'll cooperate with literally anyone. When they are attempting to do what I am doing, there is no discussion. We in that moment become allies.
The only question is if our intended outcomes actually align at all.
In this specific context our goals are an end to aid to Israel and their mutual defense treaties, possibly intervention against the Israel Government and holding Netanyahu accountable. Is that not your goal? Do you only seek the death and destruction of all of Palestine?
That is your end goal, it's not theirs, their plans go much deeper and throwing your lot in with them makes you a part of those plans, even if just as a pawn.
I'm all for holding the Israeli government and netenyahu accountable, but if I see a Nazi I tell them to go follow their leader regardless of what they happen to be saying at the moment. There's plenty of people who aren't total pieces of shit who are sympathetic to or could be converted the cause, but most of them are going to be turned off from it by the presence of Nazis.
Listen if the nazi shows up to the protest for cutting aid to Israel then his goal is cutting aid to Israel, but tell yourself whatever you like, mate. I, meanwhile, will not embrace ignorance, as that would be the path of the belligerent such as nazis.
You know Nazis also despise the left and would do anything to put you in camps if they could. They are not allies. You are falling in the exact trap described by this article, trying to attract leftists on the few subjects they appear to have in common to make the Nazis appear normal or even allies.
I'm not offering to let nazis rule the world, I'm asking for the crowd who wants to stop Israeli's bombing run and remove Netanyahu from power to be even one person larger.
