The US gun owners or 2A supporters shouldn't be aggressive or be confrontational with gun control advocates but they should push for improvements in the mental health issues & prevention of unstable people buying firearms. That is the more realistic & prudent direction IMO.
You are crazy if you think any politician or gun contol advocate is going to pay a bit of attention to that. Gun control advocates aren't interested in mental health issues and politicians will always go for the low hanging fruit...Which means that us law abiding gun owners are already under attack. No one is talking mental health and everyone is talking gun control. IMO we have no other choice BUT to be aggressive, if not confrontational, right now and right up front.
