How many people have they killed? How many have they killed in the name of Jesus Christ? Get back to me when they kill even one person.
Oh, you want to look at actual homosexuals killed. My bad, guess you have to start looking at Christian history from the 12th Century forward for that information; or, look at the laws that a Christian President signed in Uganda, in which homosexuals are sentence to death.
Of course, you can always look into sodomy laws in the US (that were only finally deemed invalid by the Supreme Court in 2003) in which the act of sodomy (consensual sodomy) could land an individual in prison for anywhere from twenty years to life, depending on the state.
You are right though, Westboro Baptish Church would never, ever support the killing of homosexuals...
