No doubt the standard whine of these groups will be the same one offered up by the Family Research Council when SPLC named it as a hate group a while back, i.e. "we are being attacked because we don't believe in gay marriage, we are trying to preserve Christian morality, we are being silenced."
That whine was a lie then and is still a lie. SPLC makes it clear that religious beliefs are not a reason why they call out these groups:
. . . the SPLC’s listings of these groups is based on their propagation of known falsehoods — claims about LGBT people that have been thoroughly discredited by scientific authorities — and repeated, groundless name-calling. Viewing homosexuality as unbiblical does not qualify organizations for listing as hate groups.
So allow me - with the help of other sources such as Truth Wins Out, People for the American Way's Right Wing Watch and GLAAD's Commentator Accountability Project - to list just a few reasons why some of these groups were named as anti-gay hate groups
