If you say:
“I’ve noticed that all you Blanks are blipity-blah. Why is that? I’m not trying to criticize, I’m just wondering.”
OR
“I’m sure not all Blanks are blipity-blah, but all the ones I’ve met just happen to be. I would never dream of generalizing about all Blanks.”
OR
“Of course I’m generalizing, but only because I want to get to the heart of matter, which is why all Blanks are so blipity-blah. Because we all know they are.”
OR
"No, of course I didn’t really mean all Blanks! Just the ones who are [some statement that applies to virtually all Blanks]. They’re the ones who are really blipity-blah!
OR
“All you Blanks are so oversensitive! It’s not like I’ve insulted you. I was just making an observation. You know, about how blipity-blah you are.”
then YOU ARE PREJUDICED AGAINST BLANKS! Quit kidding yourself, you damn Blank-hating bastard!
(Where Blanks is any group, and blipity-blah is some heinous thing.)
