That's the main takeaway the First Amendment prevents kids from buying a gun? I have not checked the gun laws of every state or all the federal gun laws but I'm pretty sure a minor can not leagally purchase a gun.
Lol I botched this post majorly but I have edited it to reflect the actual point I was trying to make.
And yes, kids canāt legally purchase a gun. The point I am trying to make that I admittedly failed at conveying is that if the 1st amendment has limitations like slander, the 2nd amendment can as well.
