Fair point.You didn't say hard left, you said "on the left".
But aside from that, I'm sure you could find a lot of fairly different trains of political thought on the hard fringes of the left.
In my experience in talking with people on the left about their political ideology, they tend to try and dismiss that they are Marxists, but then when you press them on the 10 planks they agree with all of them and will defend him.
Its similar to the “I’m not a Trump fan but I’ll go out of my way to defend him non stop and agree with almost everything he says” crowd. Lol
