"men just have stronger sex drives than women, its just biology"
"we can't help objectifying women, its in our dna"
"rape happens a lot in our society and most are perpetrated by men, towards women, and i can't tell the difference between safe men and dangerous men just by looking so i tend to be wary of men sometimes"
"NOW WAIT JUST A FUCKIN SECOND HOW CAN YOU GENERALIZE ALL MEN THATS SO UNFAIR"
I like how this illustrates the point, though I don't think it was intentional. I think the truth is that those first three "dudes" are a subset of all dudes and the last "dudes" is all dudes. The issue is that just by looking at a guy, you have no notion if he would think any of those first three things.
