The author of the memo framed his argument in exactly this way.

To quote the memo:

"As it became clear that the working class of the liberal democracies wasn’t going to overthrow their “capitalist oppressors,” the Marxist intellectuals transitioned from class warfare to gender and race politics. The core oppressor-oppressed dynamics remained, but now the oppressor is the “white, straight, cis-gendered patriarchy.”"

The author literally thinks 'Left' policies are part of a Communist power struggle.

If the above comment is toxic, then so is the original memo.
