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.
This whole idea about avoiding political discussions strikes me as very counter-productive. It reminds me of a quote attributed to a well-known person who once traveled these parts: Those who feel too intelligent to engage in politics will be governed by the less intelligent members of society.
That's not the exact quote, but I think it captures it very well.
More than at any other time, this is the time to be very engaged in political discussions, because our future is being decided right now.
If intelligent people refuse to be part of that discussion, we won't like the result.
