Maybe its’ because as a pastor he encounters those who do.
I doubt it’s who he’s hanging out with, but when people come to him, he hears about it.
Sorry, but I can not even imagine going to my pastor asking if it would be permissible to see this kind of thing much less telling him that I did so.
It is so far beyond what is good for a child of God that it would be like asking if it was ok if I roasted the neighbors for dinner.
