The way this sounds is that you are more concerned about politics as in people who take party positions and may feel excluded as a group when the majority of the community takes a different position. This is a slightly different issue i.e. party politics, and I think it is fine/a good thing, but it is also important to distinguish the two. This should essentially be under the same umbrella as personal attacks, as they are essentially the same thing.
If we discuss and use technology without considering it's ethical ramifications then we are on cruise control to hell.
To those who will respond with "he said politics, not ethics" - prithee - where is the line?
Stifling one angle of discussion stifles others.
this actually happened, as you know. "politics aren't my problem" should be called out as effectively authoritarian, as it's an admission that they'll do exactly as told.
I'm of the unpopular opinion that we should each take responsibility for our own actions, and should not act on orders we consider ethically unacceptable. I could tell you stories about a great uncle who designed dams in Austria...
