Yes, that same freedom of religion permits Christians to challenge the beliefs of non-christian cults who WANT to call themselves Christian too.
Would you respond in like manner to mormons? After all, they have 50,000 or so missionaries knocking on doors around the world telling Christians that their church is apostate and they are the only TRUE church.
One need not roll around speaking in tongues (thought you said there was still freedom of religion - or are you a bigot against pentecostals?), just open the bible, do a little reading and research.
Not really. Some of the hottest women I know are Holy Rollers. This entire thread is about hating Mormons. I have no love for muslims. So what? You want to post on a thread about hating religions, then be prepared to pony up.
