Science is always biased.
I don't like eating aluminum. I like licking armpits. I am biased.
I like the smell of ass and sweat. I don't like the smell of "fragance" that sticks to everything and smells for days like "lavender" or some.
It's not personal, and you can choose to ignore the evidence I presented. I did so for your benefit (since you have a criterion of your own). We don't have to agree, except on one thing. Chuds suck because they're assholes, not because they stink.
