The Freedom Socialist Party? Who?

Never heard of them before. And, that's after doing a fair amount of research this year. So, their critique / attack on the Socialist Equality Party and the Party for Socialism and Liberation is sketchy. Their attack in that piece on the Socialist Workers Party is spot on, as is the ones on Jill Stein and Cornell West. Here's their Wiki; they've run a presidential nominee of their own once since splitting from the SWP back in the 1960s.

That said, looking at the subsections in their "about," they appear to be strongly identitarian politics, above all on feminism, which the SEP has halfway-correctly criticized in the PSL. And, more specifically, they're Trots. See their FAQ for more.

My "vote the Commie" for the PSL is as much a protest vote against protest votes as anything else, I'll admit. I'm "post-capitalist," not "anti-capitalist," and have long noted, as have others, that Marx may have been right on description of his era, but wrong on prescription. I have gone further in noting that Hegelian dialectic is crappy philosophy and literally creates pseudoscience when used as the backbone for any theory or thesis within any social science, whether it's the original dialectical idealism or the Marxist dialectical materialism. (That applies in spades with the natural sciences, of course.)

I should add that, in post-Reagan Merikkka, I'm suspicious of groups with "freedom" in their names; these people could be a CIA front group.
