How? I truly do not go to states where open carry is a thing, for example. Guns are a controversial topic and I'm not the only one who would rather see them banned than legally purchasable.
That's a reasonable policy position to take. "You shouldn't live anywhere where you think CCW is a good idea" is not a policy position; you're just attacking someone else for either where they live or how they feel about their personal safety. Neither of those are terribly polite, and both are counterproductive towards your stated policy preferences. Nobody likes being looked down on.
