I don't understand where this term "hate" comes from?
i don't think any of it had to do with hate. in your post, the company seems to have made an honest mistake and the woman was looking for an opportunity to get something for nothing. in the case of Imas, i think he is just dumb and people like JJ and AS are looking for wedge issues to justify their existence.
Imas was an equal opportunity giver of offense, but i bet he's not racist. it was a way to stir folks up and make money. there is a Latino comedian i have seen (don't remember his name) that does the same thing but with more class. he's actually funny.
i think that in this day and age racism as we think of it, would die it's own death if there were not people who depended on it to make a living.
