Are the far right Christians here in the U.S. just upset they're losing power

In the USA at least the history of institutionalized slavery and segregation required unique federal action by Republicans to remove the racist policies of the states dominated by Democrats.

Trying to equate the Republican and Democrats of the late 1800's to what each party represents in the mid to late 1900's and this century, is disingenuous, at best. 

It is a historical fact that the more Republicans voted for the 1964 civil rights act that Democrats. That's 1964, my friend.
