I think there is a sizable minority that wants anybody who isn't in jail to be well armed, whether or not they agree with me politically, and I'm in that minority. I think it benefits society. I sort of vacillate between conservative and libertarian depending on the issue and the day of the week myself, but I think pro-gun liberals are a great addition.
I think there is a sizable minority that wants nobody to have guns, for various reasons, but typically because they actually think it'll stop violence. I think that won't work at all, and has lots of negative effects. It isn't a coincidence that all of the mass shootings happen in "gun free zones".
I think there is a vanishingly small number of people who actually want to disarm society in order to try and push a Nazi-like situation. But, imagine an America where the NSA that Snowden has told us about are the only people with firearms. Do you want to live there?
