I'm sure there are many nice, reasonable gun owners. If I lived in the states, I'd probably buy a gun myself - I think they're cool.

On the other hand, as a reasonable, intelligent adult who reads and understands statistics, I can say without any doubt they are awful for the USA as a whole. So, just like I'd ban leaded gas, selling alcohol to ten year-olds, and driving drunk, I'd ban guns. There are many, many less harmful things to go full-libertarian on than machines designed to kill people.
