I've read a few sections from the PDFs on their policy website, just normal ideas, no religious aspects as far as I can tell but I guess since its normal and insists on strengthening America and mentions support families and children they think its insanity.

Edit: Reading more sections, it supports the ban on abortion, removal of legal gay marriage, and banning of porn so I guess this is the religious aspect some are talking about, not exactly "fascist".

IMO fascism would include vast control of individual lives, abortion is murder under most circumstances (convenience), I don't think the government should be involved in marriage at all but they want their cut of taxes, and porn can be dangerous if abused but I don't think it needs to be out right banned either but even if it was my mind would not jump to "fascist".

I don't agree with everything in the document but this isn't world ending.
