What a lot of non Usians miss when talking about the Second Amendment is it was created not to be able to arm yourself against other citizens, but so that a civilian militia could effectively check the power of a tyrannical federal government. This is deeply embedded in American history and education as a final safeguard against oppression in a way we've never really considered in the UK.
I had never heard of Charlie Kirk before last night, I think I would disagree with him on most topics, but if he was saying that the Second Amendment was worth possible gun deaths, its less likely he was saying "my right to feel manly holding a gun is more important than a toddler being shot" and more likely he was pointing out that the right to defend yourself against a tyrannical government is more important than collateral damage.
If people want to fight for better gun control they need to address the actual concerns of the people fighting to keep hold of them, rather than creating a strawman of their views.
