The words "pluck the log out of your own eye" occur to me. Unlike many here, I do believe that homosexuality is a sin, but that in no way justifies violence against gays. No way. Which makes me think that there is something more to it than just a "theological" base. Because if it were just theological, then the "theological base" would be used to justify violence against other kinds of sinners, and yet that isn't happening. No lynching of suspected adulterers, no bashing of blasphemers... why?
