It's reasonable when you do it in a thoughtful, substantive way that leaves a lot of room for other side. It's not reasonable when you do it with snarky flamebait, or with low-information/high-indignation swipes. In other words, the issue isn't the content of your views, but the quality of your posts. We're trying to avoid internet default here, if possible.
