The same reason Fred Phelps is a nut job. Having a Church is a great responsibility. You are ambassadors to your community bringing it the Good News of Christ and living as an example. If the message you are relaying is one of hate and intolerance, you are no different than the ministers in the 1950’s who had a KKK robe in the closet at home.
There is nothing hateful or intolerant about refusing to respect the murderous rantings of a pedophile, and the KKK comparison is just flat ludicrous.
Being bigoted about someone because of the color they are born with is NOT the same as being leery of someone because of their choice of 'religion'.
What about having such a watered down message that what Christ said no longer matters in the face of political correctness, how does that stand with you?
