That's the thing: Prejudice is always bad, be it directly (presuming people are somehow worse or lesser than others based on some characteristics they were born with) or indirectly (presuming people are somehow better than others based on some characteristic they were born with, which means the evil types which are found amongst those people just as much as amongst the rest, get away with far more evildoing than otherwise: a great example of this being how Zionists have taken things to the point of committing Genocide because for decades they were leveraging "positive" prejudices about people who are Jewish to get away with doing seriously evil shit).

That's why I really like the Dutch take of "those things are irrelevant for judging the character of a person" when it comes to sexual orientation - it totally avoids prejudice in any form, both the obviously bad prejudices AND the supposedly positive but in practice also negative, just indirectly.

People are people are people - best not presume things about them based on traits that have nothing to do with how good or bad they act, even "nice" presumptions.
