Of course he's gonna have porn. A lot of religous people use porn. Porn is a major problem in christian homes. They are married to these uptight spouses that wont even meet them half way in bed. You wanna keep your man from watching porn? Do something sexy with him.
But all in all. If your preacher is watching porn, he's not in tune with the spirit. But still, watching porn is better than most of these corrupt preachers who molest kids.
