Re-read what I said, specifically, I'm addressing the reflexive hand-wave of fascism as an all-too-common way to suppress thoughts we find distasteful rather than actually engaging.

That's what wartywhoa did to a commenter who was in no way suggesting a fascist view.

That's not worse faith, that's simply pointing out that aligning your ideological opponents with Hitler is intellectually dishonest.

In this you and I agree: "dismissing all criticism because it draws a parallel you don't like isn't reasonable."

There's nothing more thought-suppressing than dismissing all equation to fascism as thought suppression.

If we actually agreed on the principle, you wouldn't be engaging in the behaviour.
