I really think there are multiple parts to this entire thing.
First, should someone take such a job. I’m reminded of something I’d heard about a shul in Denver. There was a shul there which was the last OU shul without a mechitzah (it was grandfathered in under their old rules, before they required one). A YU musmach was offered the position of Rabbi there. He asked R’ Herschel Schachter about taking the job, as he was hesitant due to the mechitzah issue. R’ Schachter told him to take the job, to try and encourage the membership to install the mechitzah. However, he told him that if he wasn’t successful within a few years (I don’t remember the exact number), then he must leave. That was what happened – they still refused, and the guy left the job. When they tried to get another YU Rabbi, they couldn’t. R’ Schachter had instructed his students not to go there. The shul ended up hiring a YCT musmach. So we see that it can be allowed to go to a shul with big problems, but with strict guidelines, and with the right intentions. I don’t know what the intentions of this Rabbi are, so I can’t really judge.
This leads to my second point, which is the treatment of this community by the Jewish world. I think that the mindset does have to change in some ways. Many Jews look at these people as disgusting, and completely cut them off. I think we need to stop doing that. These are people who have a terrible nisayon, probably one of the most difficult anyone can have. They have urges to do things which are completely forbidden by the Torah. If they want to live frum lives, they are doomed to never marry, never have children, and be alone for their entire adult lives. This guy is correct when he states that they often have no spiritual guidance. Why should that be? We all do things wrong. We all speak lashon harah at times. Was anyone here never jealous of someone? We all do things wrong. Who is to say what aveiros are worse than others? You can argue that lashon harah can be worse, because it’s bein adam l’chaveiro. These people need someone to guide them so they can live a religious life, where they can be accepted. We obviously can’t tell them that their actions are ok, but there are lots of other mitzvos they need help with. Why should they be denied that?
Again, it all boils down to the intentions of this Rabbi. We can hope he has the proper mindset.
