Wow good point, oh... no... wait... American isn't a race... Nice try though. Now you're thinking "Wait, isn't one kind of discrimination the same as another?" Nope! See, discrimating based on race is just plain wrong, since a person's race has absolutely nothing to do with their values, personality, or pretty much anything except what they look like. Discriminating based on something like culture, which is still wrong, has basis because someone's culture has a big influence on what they think, say, and do.
If you like, let's bounce it back: Cougar is discriminating against every "race" except American, saying they are inferior, and that's why they're mad. So they're not making valid arguments based on facts, they're just stupid and ignorant because they didn't have the luck of being American. OH WHY HAVEN'T WE SEEN THE LIGHT. SORRY MASSA, Come on everyone, let's get back to the cotton fields, since we're obviously too inferior to do anything except slave labour for the great Americans.
