"....they may take it as gospel..."
If anyone takes license and assumes Rev. Graham was not being polite and showing a generous level of class, but rather serious they are undeniably blind.
I'm sure Christians and conservatives alike will believe liberals when they say, "You see!, even Rev. Graham supports them. Therefore right-wingers were wrong all along, and this great couple is vindicated."
Your last line is what concerns me, TJI. I can surmise there are those who don't take it as a generous level of class like you said, be it Christians, Conservatives or ANY other political or religious class of people and they are indeed blind.
