seriously this happens a lot people will go off and say word for word that a whole group of people are evil and bad when its a subset of a group. When called on it they may simply say that its not talking about the group as a whole or “not for you” if they dont genuinely believe the whole group is bad (which is wrong and discriminatory)

The issue is the discrepancy of what you say in relation to what you mean will lead others to believe in what you say but not what you mean and this harms those just trying to survive normally.
