How come libertarianism is considered a childish philosophy?
Typical Team Blue vs. Team Red monopoly tactic.
It's harder for the left to demonize libertarians as evil thugs (since they don't fit within the "blood for oil" or "iz muh body you old white man" talking points), so the only way to prevent possible Democrats or liberals from defecting is to just dismiss the ideology off-hand. Like how whenever someone says "hey, maybe we should ask ourselves if this particular law is necessary" the typical bs lefty response is to start shouting "SOMALIA" because apparently you can either want all government (minus abortion regulations) or no government whatsoever. When a libertarian points out how stupid and hackish that logic is, its much easier to just double down on "you don't know anything. You're so immature. Your beliefs are extreme because they aren't our beliefs you child. Libertarianism only works in regards to issues WE care about."
Yes. As we all know, defections to the Libertarians are a very real and present threat for Liberals and Democrats. This is evidenced by the fact that Libertarianism is a huge ideology with a huge following and a huge, credible threat to the Democratic and Republican parties.
Also, that quote is a bit odd. Democrats and liberals don't apply Libertarian principles. Rather, Libertarians apply liberal principles. Remember who came first.
