Poor choice of words, perhaps. I meant those who generally share your political opinions in other respects. For instance, "anarcho-communist" or "libertarian"
I don't think so. Labels only have so much resolving power. They represent people who are broadly aligned in values, but not necessarily on every specific issue.
For instance, I think most libertarians have individual dissent from their norm on various topics. It should be easy to find examples in the case of libertarianism, but I believe this applies to other political ideologies too.
"Libertarian" is far more broad than, say, Marxist-Leninist or Anarcho-Communist. When you go from "Marxist" as an umbrella to "Marxist-Leninist" as a category within Marxism, you are generally conforming to that specification's tendencies. At that point of specificity, there are more "solved" questions than unsolved.
