The people jumping to conclusions about your politics due to your views on guns are just playing the odds. There are a lot more conservatives defending gun rights than there are moderate democrats doing so, and there are a lot more of those than there are far-left people (like myself).
Basically, if someone says they support gun control, it's a very safe bet they're in the center-right political band that the Democrats cater to. If someone opposes gun control, while there's a chance they're a " “Under no pretext should arms and ammunition be surrendered; any attempt to disarm the workers must be frustrated, by force if necessary” -Marx "--type socialist, by sheer numbers it's far more likely they're supportive of the conservative regime.
