I'm not really PROUD of any community - ones I'm a part of or not - as every community has that vocal minority that ruins everything for the rest, and tars and brands their image. There are communities I ENJOY being a part of, such as the Brony community (they're a lot of fun, and ALWAYS have a charity going on somewhere). And there are groups that I don't enjoy being a part of but still am, such as Christianity. I like being a Christian, but the thousands of conflicting beliefs, misinterpretations, scandals, and ignorance spread throughout the group has made me feel an outsider in my own collective faith. Then again, I have a lot of... er, "unique" beliefs that also set me apart from the "herd", so to speak, but nevertheless a wedge has been driven between me and the Christian community.
So, in essence, no. There is no group I would be comfortable with shouting from the rooftops that I am a part of.
