That is such an ignorant statement. Not all trolls live under bridges. That would be like saying that all of "the black people" live in the ghetto. Many of the trolls that I know live in Norway, and make their homes in the mountains, near the Fjords. They may occasionally bother a farmer, and kill some of his livestock, but overall they tend to keep to themselves.
I believe in civil rights and equality for everybody, except for "the homos." Trolls are people too, and it's blatant anti-trollism such as this that divides the world.
