> People like to say it's just a few bad apples, but it's far more prevalent than that. Not discounting your point at all, but the best response when someone says this is to point out that the saying is "a few bad apples spoil the bunch". It's very literal- an apple that's going bad releases fumes that cause other apples nearby to spoil. So it's very important to find them and get rid of them before that happens. Completing the analogy is an exercise left to the reader.
