"Established in 1955 by
Pastor Fred Phelps, the Westboro Baptist Church (WBC) of Topeka, Kansas still exists today as an Old School (or, Primitive) Baptist Church. We adhere to the teachings of the Bible, preach against all form of sin (e.g., fornication, adultery [including divorce and remarriage], sodomy), and insist that the sovereignty of God and the doctrines of grace be taught and expounded publicly to all men."
Compare that to what you posted above:
"You don't know what your talking about. Homosexual sex is a sin, Abortion is a sin, Sex outside of marriage is a sin, Adultery is a sin."
How is that not different? Tell me where you disagree with him. Quote from that first paragraph.
