I’m all for helping everybody.

I was already never much a fan of the word “solidarity”

and there we have it. The greatest threat to all leftist thought it capitalism, and to be unwilling to stand against it in solidarity is what is needed before we devolve into attacking other leftists. Funny also that you’re willing to question anyones leftiness if you don’t agree to their flavor.

Fun cherry picking portions to pervert and misrepresent the original meaning by stripping the rest of it, losing more than context, and inverting the meaning, doubling down on fallacy. Fun misrepresentation putting words in my mouth and asserting what my will is, that's completely unfounded and untrue. Way to miss the point. Way to go off half-cocked and pointing fingers, projecting, oblivious to the three fingers pointing back, doing the very thing in the accusation. I merely said "not my left". I didn't do and would not do what you you insist I'm doing, like you're doing. Are we not allowed to have a particular perspective? Seems implausible. Like we're to have it all be our left... from kropotkin to stalin to half the purple party to hitler to marx, all the same? No. That's still not my left. Any of that not being my left does not mean I'm questioning anyone's leftness for not agreeing with my leftness. Especially where my leftness is. How would that be a tenable internally consistent logic to have such an authoritarian imposition from such a libertarian left position? See?

Also, methinks you may have typo'd a bit... hard to parse:
