No, prejudice is bad, full stop. By definition it means to judge someone for something before you actually know for sure that they have/do the thing that bothers you. It doesn’t matter what the thing is, that’s not the problem or the point. The point is you can’t, or shouldn’t, view or treat someone as though they have some quality you dislike when you don’t actually know about this individual and only know that a high percentage of them do. You can’t judge an individual this way! If you hate waste (as do I) and you feel trucks contribute to that and that a majority of truck owners don’t make use of their trucks, then great! Speak about it exactly like that. But you can’t simply take any truck driver and say “that individual is wasteful” without knowing.

You can’t do that any more than you can assume my friends and I are criminals and drug dealers because at some point we decided to use Telegram as our primary messaging app, or like ICE can assume anyone standing near a pro-Mexico protest is an illegal immigrant, you cannot attribute a quality to an individual without having actual knowledge of it.
