Hi Wild Cat. Welcome!
You may be surprised to find this out, but you're far from the only liberal here. There's a pretty good mix.
You're also unlikely to get any argument here that the right to keep and bear arms should be completely unrestricted. If nothing else, pretty much everyone will agree that weapons capable of large-scale destruction are simply too dangerous to have generally available. Anyone who thinks, for example, private citizens should be able to own nukes is just crazy. So, clearly, the issue isn't whether or not citizens should own any weapon, but where to draw the line.
You might get some argument on automatic rifles, though. I think most would happily accept the NFA requirements of registration and licensing for full auto weapons, as long as the FOPA ban on post-1986 MGs were lifted. We've had fully-automatic weapons in civilian hands since they were invented, and once the minimal restrictions of the 1934 NFA went into effect, the use of MGs in crime has been effectively zero. Since experience shows registered, legally-owned MGs pose little or no danger to safety, why should they be restricted? There's also the issue of the purpose of the 2nd amendment, which would seem to imply that citizens really should have the same small arms that the military uses.
Similar arguments apply to so-called "assault weapons". Absent evidence that they're an actual risk, they should be legal. So say the libertarian-minded, anyway, and most of the conservatives as well. IMO, the reality is that the reason many liberals want to ban them isn't because they're dangerous, it's because it's a small, but easy step toward a total gun ban.
Another issue you might find debate on is whether or not convicted felons should be denied the right to own guns. There are plenty here on both sides. I find this one interesting because I would think liberals, who tend to believe it's possible for a criminal to reform, should support reinstating the right for those who have paid their dues, but liberals tend to be even more strongly opposed than the strict law-and-order conservatives (who also tend to be opposed).
Similarly, there are plenty here to believe that the right to carry, concealed or not, loaded or not, should be universal -- no permit required.
Finally, the biggest point of discussion, I think, will be over support for democratic candidates who are unabashedly anti-gun. I notice you haven't tried to address that point head on ;-)
Again, welcome. Here's to some interesting discussions -- even if they're just rehashes of old debates
