The long term trend over the last 200 years is gun advocates are slowly losing. As someone that enjoys shooting that does bother me, but don't expect public gun ownership to be a thing in 200 years without some fundamental changes.
Personally, I would focus on winnable fights. But, politically having red flag issues tend to get out the voters.
Technology has changed too much to make any sort of reasonable comparison of gun politics today with those of two hundred years ago. Certainly the national mood has shifted toward fewer restrictions on guns over the last generation.
If you want recent comparison then while gun technology has changed little, there has been a 10+% drop in private gun ownership from 1961 to now. Though there is some very high error bars on those statistics. Hunting has also become significantly less popular.
These really are significant shifts is public behavior. And eventually public attitudes really do influence politics.
IMO, advocating for the rights of gun owners is a losing strategy, you need to promote gun ownership.
