Well, I suppose it's only natural to critisize authority, so I guess as long as it doesn't sound dickish I assume it would be okay.
My personal opinion is that the mods do most things right. Every site has something some people don't like about it.
Personally, I think it's the right decision to delete content from the site that might be detrimental to the site's well being.
Remember the Google fiasco? If we're talking about a controversial topic and it starts to harm the site's standing then the proper thing to do is delete the content.
On the other hand
I do feel like some rules are too ambiguos for their own good. Like the anti-troll policy. It can be difficult to what is trolling and what isn't, so is it really fair to say it's our fault if we fall for it? Shouldn't it be the troll's fault?
Another one is the "No being a dick". What is being a dick? Under who's opinion? I personally don't like rules being in limbo. I prefer something akin to a legal document, like a signed To S
But that's just me. I can live with what we have right now.
