That's more complicated, supporting intersectional liberation is no doubt an important part of any socialist movement. But if there is an overemphasis on bringing about attention to identity politics over class based conflict and inequality then that could be a problem.

I guess the best way to tell is how they propose this liberation is supposed to come about. If its the same pointless rhetoric you see from liberals such as pushing meaningless diversity quotas or supporting charities and whatnot, then they're approaching it wrong.
