Conservatives are troubled by the Sunday coming out of Michael Sam, a college football player and a solid NFL draft prospect.

Rush Limbaugh on Tuesday characterized Sam's coming out as proof that heterosexuals are “under attack.”

“Heterosexuality has no political agenda and there is no agenda attached to it,” Rush told his radio listeners. “Heterosexuality does not have activists, but they're under assault.”

“Why is it okay now for a gay man to play football? I thought it was dangerous and leads to concussions, that it was barbaric,” he added.

In a Christian Post column, Michael Brown accused Sam of perpetuating a “selfish act.”

“Looked at from another angle, it was more of a selfish act, and not only in the sense that Sam is suddenly a national celebrity. … What I mean is that professional football is all about the team, and the focus must be on making a joint sacrifice in order to win rather than drawing attention to oneself,” Brown wrote.

Brown added that “with the 'bromance' type of close relationships that many players enjoy, would they be as physical and free with a homosexual teammate?”

In an article published on Charisma, Pastor Ron Cantor warned that a gay teammate “is going to make for an uncomfortable situation” in the locker room.

“How ironic – in the past it was the homosexual who was afraid to come out,” Cantor wrote. “Now it'll be the guy who doesn't want to take a shower next to the homosexual who will be shunned and shamed – and he will be told to keep his mouth shut.”
