Yes, "evil" and "stupid" are value-laden terms.
Yes, they are emotion-laden terms.
Yes, they are often used for no other reason than tribal signaling.
Agreed, the Raiders' opponents (football, right?) are not evil.

I can't tell if you're actually claiming that there are no evil or stupid people in the world.
You don't say it explicitly, but it seems to me an implicit assertion in the fact that you chose to make the statements you did.

If you are, I disagree with you about that.

As for being subsets... evil people value different things than I, but not everyone who values different things than I is evil. Stupid people make different assessments that various things will go wrong than I do, but not everyone who does that is stupid.
