I think it’s more often than rare. And coming from prejudice and bigotry is not mutually exclusive from not majority traits. In other words, just because it’s not majoring traits does not make it necessarily bigotry and prejudice. Sometimes negative stereotypes do. A bigot is unlikely to be completely honest about the thing and will embellish or just make **** up. But not all stereotypes derive from bigots. And not all the ones derived from bigots are false.Very rare. Stereotypes generally come from prejudice and bigotry not majority traits.
Every single stereotype I’ve applied to union workers I’ve experienced myself working with them. My outlook on unions comes in part from that experience.
The error with stereotypes is applying it to everyone in the group, not that stereotypes exist at all. In the case of my experience, it’s not even a majority. But it’s not an insignificant minority either.
