Some do. Others are like some posters here, who just want to confiscate them and be done with it.

That's true - but that doesn't mean they're not motivated by a desire to stop firearm deaths. If you actually get rid of all the guns - not simply adopt legislation to do it but actually do it - then you end up virtually eliminating gun deaths:

finance.yahoo.com - Japan almost completely eliminated gun

There are lots of things that one can argue about that policy. But it's not really fair to claim that "it's not about guns," as you suggested upthread. People who value having a society with ready access to firearms might suggest lots of alternative approaches to gun violence that don't involve eliminating firearms, which approaches might be rejected by those who advocate for disarmament - but that doesn't mean the latter aren't motivated by a desire to solve the problem of gun violence. It simply means that they favor a different solution than 2A advocates do.
