The only way to know if Americans love keeping guns or not is by doing a refurundum. Since most cons don't believe in polls lately.
The growth of other minorities, the youth voters and the decreasing of the conservatives nuts and close minded older whites will difinetly have an impact on future of guns in this country...is inevitable
The poll I linked was from November of 2017, so read it and tell me what you think. All you need is two thirds of the House and two thirds of the Senate to approve eliminating the 2nd Amendment then 3/4 of the states to ratify the repeal of the amendment.
Also, if you would have looked at the poll, in 1959 60% of Americans favored a gun ban, now it is only 28%. So, you have a long road and a long time to change opinions. What is interesting is that although gun ownership is under 50%, 71% oppose the banning of guns.
