If we all removed all the posts we disagreed with there wouldn't be any posts left ;) If eds are removing posts it is because they breach the editorial policy:

We put up with a lot of foaming-at-the-mouth right wing trolling around here because, unlike the NZ state, we can actually tolerate people having wildly different views from ours. Comments on this site represent the person posting them, not the volunteer collective that runs it. If you want to embarrass yourselves by supporting the expanding police state, be our guest. But don't expect much encouragement from other posters.
