Why should you care for people, who support gun control laws? If you would care for someboidy, than it would be gun-loving people who are a minority over here, and do not have the votes to change something about it. I live in a country, where the laws have been fairly liberal until 2010, but since then it is going downhill fast. Gun ownership is relatively common, but about 75-80% of gun owners are hunters - and many hunters only care for huntin. They fall for the same BS as everywhere else when politicians talk about "dangerous assault weapons" etc.
We who care are active in lobbying groups, we donate a lot for the cause, but sadly do not have real support in any of the political parties, which is why the effect of lobbying is limited. If you don't want to care for us thats fine, but please understand that there are millions of europeans who love guns just as much as many americans do - there are just a lot more who don't, which is why the laws are the way they are.
