The polar opposite of the fearsome Conservatroll. The Libtroll spreads guilt complexes by invoking flaky sociological theories with no basis in reality. If you're not sure whether someone is a Libtroll, politely disagree and see if he calls you a racist. Libtrolls can also be identified by their hatred of the West, their liberal accent, and the overpowering stench of white guilt.
Ignore anyone who uses terms like 'power structures,' 'patriarchy,' 'privilege,' and 'oppression.' They're probably a Libtroll.
