You can't just group people up and assume/act like they are all the same. There are always those that are different in every sense of the way. Hating on someone over a statistic is fucking up peoples lives and it's not even their own fault. How's that a good thing?
Firstly, everything you just said is an assertion.
But I will respond in good faith anyway.
Pattern recognition is a very good thing.
Even animals use it.
One could even argue as to it being a necessary prerequisite to survival.
Also, one good apple doesn't unspoil the bunch.
