Politico says:

Republican National Committee Chair Reince Priebus on Wednesday reiterated that the Republican Party believes marriage is between a man and a woman, even as he called for greater tolerance in the GOP.

“I know what our principles are, I know our party believes marriage is between one man and one woman,” Priebus told MSNBC’s Luke Russert. “But I also know our party’s going to be inclusive, and it’s going to listen to people and it’s going to allow for differences in our party.”

So they're inclusive unless you're for gay marriage, in which case you're fighting against the principles and beliefs of the party. One of two things is happening here. Either Priebus doesn't understand what "inclusive" means, or he doesn't think people who support gay marriage are real people.
