You demonstrated the ineffectiveness of the approach by assuming I'm a Democrat or even American.

Actually I assumed you're a lemmy user, of which I've yet to meet one who doesn't generalize republicans whether the poster is american or not. Not without reason, mind you, many republicans are say, racist, though many are not. It serves as a damn fine example of exactly what I'm referring to and is also a generalization in and of itself, which doubles back to make my point again. I understand the process, and in fact at times see value in it rather than simply nature at work, the trick is knowing what to do with the generalization. Should you hate X because X usually Ys? No, but if Y is an undesirable behavior trait in X you should at least find out if they Y before becoming entwined with them somehow.
