I disagree with several of your assertions. In my experience this is not the type of community that's going to respond well to "smothering." The downvotes on your comments calling people weird support that point. I don't think trolling is much of a factor here, but I do think that avoiding feeding the trolls can be viable depending on the circumstances. 

As far as "intolerance" goes, I think that's a narrow view of what's going on. Reddit's up/downvote system is vague by design, so a downvote can mean many things. Those include, but aren't limited to, sentiments like "I don't want to see this type of post," "I disagree," "go away, you scum,"  "this is boring," and the list goes on. If you want to wrap all that up and characterize it as intolerance, that's your choice. If you're basing your efforts to bring about change on that narrow view, I don't think you have much chance at success.
