mk... many of us are not saying we're offended by the joke, just that it had no place on this forum. If I said "All blacks are no-good criminals" or "women's only use to cook" (which is completely false), how do you think that would go over?
And people have a right to get offended... it's really not up to you to tell people what they will be offended by and won't. And it's not like this was just a little passing comment, it was a derogatory joke aimed at mexicans.
Anyway, I think the joke was removed for good reason, even if it is considered funny by some :]
