My comments and the links were all about the stereotypes part,not really the pitbulls

Exactly my point. Nobody is talking about any stereotypes.

A counter argument was made that such a judgement doesn’t count for dog breeds

If the discussion was about how “X people tend to get Pitbulls”, I’d agree that talking about stereotypes makes sense.

But the discussion was about Pitbulls being bloodthirsty and dangerous. It’s not a stereotype, it’s a biological fact.
