No, you're misinformed.

When the left or the right says:

So and so is a this, a that, and some other negative sort of person (or
group), that is hate filled rhetoric.


When the left or the right says:

So and so holds an incorrect perspective on this issue because........,
that is a first amendment right to an alternative viewpoint.


Lumping an entire class or group into a statement made to cast that
class or group in a negative light nearly always precedes hate-filled
rhetoric.
