"So now cite a source that the church involved is made up of conservatives as Libs claim."
OK. The church sponsoring the burning is the Dove World Outreach Center. Here, from their own web site, is a post showing their participation in a joint protest with the Westboro Baptist Church, best known for picketing the funerals of US soldiers and sponsoring the website godhatesfags.com. The march seems to be a rather confused protest against homosexuality, Islam, Barak Obama, or all of the above.
"This is about like asking for one conservative who argues that Muslims do not have a legal right to build an Islamic cultural center close to ground zero."
Actually, rather more than one conservative believes that. The poll linked below shows that 39% of Republicans believe that the owners of the site have no legal right to build a mosque. That's a minority, but much larger than the number of Democrats or independents who agreed with the same statement.
So you see, liberals actually can cite sources, because we're talking about real things. Still nobody, I see, citing a source for the imaginary claim that any liberal has said that burning the Koran is not protected by the First Amendment.
