Very good point. I'm not trying to judge (I don't think I am, but I'll pray about that), I just feel sorry for their families if any harm comes of this. I also fear that Christ may be marred in the minds of those who may see these ministers entering or exiting a porn convention. While they may not be sinning against their own bodies (sexual immorality is the only sin that is committed against one's self) they may cause another brother to stumble.
I make mistakes in judgement also. I would hope that someone would raise their concerns with me if they feel that I am misguided. I believe that is called accountability, not judging.
If God has indeed called them to this ministry, then they will know it and should not heed anyones concerns.
Good point....again, I don't know of many men with the strength alone to avoid giving into temptation in that environment. It would take every single bit of Christ-in-me to overcome.
