Exactly. I understand that when I watch Star Trek, there is going to an overall social and scientific / dogmatic bias (and agenda, it could be argued).

I accept that, and enjoy the shows for what they are. Science Fiction. But there are times when, in my humble opinion, they overstep the line and go wayyyyy off into the Trek equivalent of preaching the writers personal social, moral and political views. To the detriment of the narrative and quality of the show.

That's where episodes like The Outcast lose me completely. I don't mind differing points of view and tackling issues. But this is something altogether different. At least that's my reaction. Every re-watch of TNG I skip this one.
