I haven't been following political discussions very closely, but I think every single time I've seen bans in political contexts here, they've been deserved. Sometimes the bans have come a bit easily, but even then they've definitely been deserved. Obviously I must have missed a ton of bans, so it's possible there's some undeserved bans there too, but based on what I've seen, I have little reason to suspect that to be the case.
I reckon the issue is that people don't want to be entirely civil about their opinions, because people tend to not be entirely civil when discussing politics. If that's the case, the real question would be whether some leeway should be allowed even if in practice it means racism, sexism etc. My moral stance is absolutely not and people should learn to be civil even in disagreement, but my pragmatic side isn't so sure - people are what they are, and trying to fight it too hard also has a cost.
