Comment by Eisenstein

I'm sorry that I misunderstood you, it seemed to me that you were trying to invoke a 'gotcha' in that the commenter's lack self-examination in how they may have been in a similar dynamic invalidated their judgment of others.

With this explanation as context, I don't think the commenter was attributing it as a left vs right issue except that the targeting was being done by right-wing groups.

I think a paranoid world view, broad rejection of evidence, and othering of groups based on existential fear are hallmarks of the right-wing and regardless of initial beliefs can only manifest themselves as such. Thus it is natural that such messaging, once internalized, would lead anyone to be clearly viewed as no longer aligned with anything except a right wing view.
