Like the poster above says, the second amendment is highly unlikely to ever be amended (yes I see the irony too) under a Republican president as they nearly always accept money from the NRA to help fund their election campaigns. Their political system is even more flawed than ours, it is only possible in the USA to win a presidential election with substantial funding from private sources, the winner then has to act in the interest of these sources when they are elected. It’s why Trump could never relent on his position that the second amendment should remain as it is, because he accepted huge funding from the NRA during his campaign.
On the subject of whether the second amendment should be changed or not, I don’t think it’s really the issue, there are so many fire arms in circulation in the USA now that it just isn’t realistic to suddenly take them away. The issue is more centred around the lack of regulation when it comes to purchasing fire arms imo. This latest mass shooter had severe mental health problems/violent tendencies and they were in the system, any brief check into their background would have shown that giving this person a gun would be creating a ticking time bomb. Yet they were able to purchase fire arms legally from FIVE (yes five) separate stores to carry out this attack. How is it logical to live in a society where you have to meet strict criteria/regulations to operate a motor vehicle, yet anybody can purchase a gun at their local store?
I am very anti gun and in an ideal world think it would be better for everyone if they weren’t there at all, the life of even one child should be enough to support this position, let alone the many hundreds who have needlessly died. I just don’t see how you suddenly remove tens of millions of fire arms from a society/culture that are obsessed with them.
