Ugh ugh ugh.
And I'm ditto-ing the suggestion that this thread be locked since it's already going in "that direction."
The bottom line is that we as Greeks are under a microscope because of the history of our organizations and the stereotypes. We HAVE to be more sensitive to these kinds of situations, or we will just continue to promote the stereotypes that we claim we're nothing like.
IMO there is a huge, huge difference between a "fiesta"-themed party with a pinata and cactus decorations and some Dos Equis . . . I mean virgin daquiris

. . . and one where the tickets are shaped like green cards and there's a drunk Mexican passed out on the website. Something like the difference between calling someone "Chicano" and calling them "wetback."
Also, I don't understand how so many people can get to college -- or in many cases many years beyond it -- and not realize that there is something called "cultural context." You can't compare stereotypes of drunk Irish with stereotypes of drunk Mexicans. If you do you're missing out on a whole bunch of historical AND current issues that -- gasp! -- yes, do affect race relations today.
