I think the fact that there is a variety of opinions being posted, compared to the censorship I witnessed on Reddit, is the more mature situation. If anyone is being childish, it's those who feel the need to censor opposing ideologies. Feeling free to post and discuss differing views has a lot of value. I am assuming by your use of "commie" that you'd rather dismiss an entire ideology and group of supporters outright rather than on any real grounds.
