If people who live in america hate it so much...?

have you studied psychology? There's a period of childhood development called "oppositional bonding." Its around 2 or 3, when children love to say "no." Doesn't matter what you say to them, or how you try to reason with them. "No." Most liberals are cognitive children and just react with a "no" against their parents/authority figures. You can't reason with them.
