Oh well that makes it ok then. If I find a clear correlation between say black skin and employee underperformance, I guess I can just go right ahead and sack individuals based on some statistical association discovered in a population they happen to belong to.
What the fuck is wrong with you people? I mean the entire lesson of not being racist or not being sexist or whatever is that it isn't ok to judge individuals by the population they happen to belong to. I mean guess what, black people are more likely to be criminals. Women are less likely to be coders. White people are less likely to play basketball well. These are statistical facts, though it seems awkward to say them. But that's ok, because the entire point is that you assess each individual you meet in life on their own merits, not some statistical generalization.
And somewhere along they way, you've missed this point. You don't get to assume that an individual is a shitty employee because they are a shitty LoL player just because you have some correlation to go on.
