I don't think they're fascist, just selfish in most cases. They take the "me" in "Don't tread on me" too literally, and only care about their own rights and their own needs, fuck everyone else's.
Their Venn diagram of "Things the government should provide/allow people to do" and "Things I personally need/want to do" is just a circle, and they won't lift a finger to try to shape the government to work well for anyone else.
