Well, it's an American law, so its validity has no relation to how non Americans see it. Also, the activist pressure is much stronger and much, much better financed on the anti gun side, so that does not make much sense. You can go read the recent SCOTUS decisions related to the 2nd amendment; their interpretation of the constitution is very, very well justified. You can disagree with it, but it's ludicrous to say it's all because of extreme activist pressure. The 2nd Amendment is pretty clear on its intent, and that's wildly agreed on by constitutional experts. Americans usually support the right to bear arms too.

I'm not American but if I was and I wanted to limit access to guns, I don't think arguing that the courts should decide the 2nd amendment doesn't actually give the right to bear arms would be the way to go. If you think Americans agree with you and don't actually want that part of the constitution, judicial activism wouldn't be needed.
