By "religious right" (a term I have never heard before) do you mean more traditional churches like Baptists, Lutherans or Presbyterians? Or evangelistic sects like those in the style of Joel Osteen? Or do you mean the most traditional Christians, the Catholics?Most of the objections to the LGBT community come from the religious right which use the writings of Paul (I believe it's in Romans) and the Old Testament books of Levitticus and Deuteronomy to justify their discrimination.
In any case, a religion is not a political party.
A belief, as unfounded as it may be, is not discrimination per se. For example, as obsolete and wrong as it might be, the caste system in India is a cultural "belief" and is the truth to them
