Okay, how come it's always the people who are *supposedly* against Sharia Law that constantly fill your Facebook feed with some pretty similar-to-sharia law stuff?

Always seeing the same guys posting about "an eye for an eye" or "going back to the biblical ways" for dealing with thieves, or wanting the death penalty brought back, all crap like that. Then they post their conspiracies about Sharia law creeping into western civilization.
