For whatever reason, all politics is now identity politics. Less important than the effectiveness of a policy is whether that policy is threatening to the ideology that accompanies a person's group identity.
It makes me wish we didn't have names for these things for people to rally around. If you replace "I'm a libertarian" with "I'm skeptical of government solutions without sufficient supporting evidence" notice how the lack of abstraction makes it impossible to avoid focusing on the issue at hand.
I'll every once in awhile throw a jab towards "libnerdtariasm", because while I do try to keep politics out of things as much as possible, I am still easily baited by nerd tropes.
This is a good point. I'll keep it in mind for the future. On less civil sites, it also at least makes someone work to invoke a string of identity-politics nonsense like "LOL LIBERTARIAN MOAR LIKE STRAIGHT RICH WHITE MAN AMIRITE?"
