"Talking to you about politics always feels like an interrogation about my beliefs. You're never satisfied with what I say, you always make me clarify it a dozen times."
The biggest mistake I've made as a libertarian is mentally injecting "for everyone" into others' rhetoric about liberty without hearing them say it first.
They said "cut spending," but they meant "except for the military."
They said "smash government unions," but they meant "not the cops."
They said "don't tread on me," but they meant "unless I'm Mexican or Muslim."
They said "mind our own business," but they meant "unless it's Israel."
They said "our rights come from God," but they meant "not at the border."
So yeah, I now make it a point to resolve ambiguities I see in that type of argumentation. Sorry if it feels like an interrogation, but I think libertarianism has suffered greatly from an excess of charity in resolving conservative/conservatarian ambiguities.
