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.
The hysteria of thinking that we (the US) are one or two steps away from a police state is exactly why I support the notion of political bans on my computer related news sites.
And if you live in a country that is approaching a real police state, I would guess there are more appropriate locations for discussing your political situation than HN.
