Just figured I'd say something a little different, since a lot of these sort of discussions are a product of similar behavior.. similar actions.. similar reactions.
I've realized that people generally follow an order because it allows themselves a sense of continuance or reliable way to believe in what they think they are.
Also, most people are shaped to act specific ways based on expectations others place on them. So a lot of time, people might believe they have to satisfy other people's expectations and live up to them, etc. When people don't it can cause distress in the traditions, etc, because it creates a sense that things aren't following along or continuing in a predictable manner.
I think most people have expectations about various things, and these preconceptions often determine how we choose to define ourselves or try to define others, etc..
Now, considering construct, there are a lot of people focused on it and wrap a significant portion of their life around it. So there will be a pattern that develops and people will want predictability and reliability. Also each person has their own expectations and needs/desires, etc.. and they'll chase those regardless of the desires of others, etc..
If you're in charge of a large community, all of the differing opinions essentially become noise, and it might be difficult to really listen to it precisely. I think that is what creates frustration for some people using construct and trying to engage in discussion, because everyone wants to be heard(why speak if you don't expect a response?).. And often most people don't see a broader picture because they've been following their own patterns and direction.
So scirra can censor, sure.. We all censor each other in our own ways when we don't want to respond or take part in discussion, etc, or when we disagree, we may try to change other people's opinions by arguing, etc.. That's part of discussing etc.. I think it is fine, and something people eventually learn to accept. It maybe be unfortunate though in some cases, as everything has reactions/consequences. I particularly believe, it'd better to just let people discuss stuff, otherwise they'll just go discuss somewhere else and worse feelings can develop, etc. We're all just results of our conditioning in our minds, etc, and at the mercy of our physiology usually..
