ganymede, let me say first of all, I am a small "l" libertarian. And you sound like one yourself.
Secondly, liberals aren't inherently anti-gun. There are a couple of communists I've known that are in fact very pro-gun.Being on the right is no guarantee of being pro-gun.
Basically, in addition to right and left, you also have authoritarian and libertarian. Authoritarians are the people who want to tell you what to do with your life, how to do it, when to it. I don't have any use for these people, and in my mind, their elimination is the best use of a gun.....
They can be right or left. It matters not whether a person's authoritarianism is driven from a desire for peace, love, and humanistic virtues, or if it is driven by religious extremism, or corporate policies, etc. Authoritarianism is what you are really against. There are those on the left who aren't very Authoritarian. And they also tend to be more pro-gun. There are those on the right (look at the last administration) who are more authoritarian. They tend to be less pro-gun.
Now, as a general rule, there are probably more libertarian shaded conservatives than liberals in American politics, but you shouldn't discount anybody who wishes to leave you alone, regardless of their own personal beliefs, or lifestyle.
