Dave, you would not even lie about being friends with perverts.
You have no reason to call him a liar, but it would still show that he does not consider gay folk as perverts anyway.

Your accusation is baseless, and clearly false.

He disagrees with SS marriage and says so.
There is nothing wrong with doing that.
His statements about promiscuity and infection rates are factual.
He does not denigrate anyone for being gay.
You should all get off his back and stop persecuting the man.
