I feel like the gun control debate is particularly relevant - whenever a shooting happens one side calmly says "This is unfortunate but unavoidable given the cost to freedom we'd need to pay to remove firearms - please stop trying to use a tragedy politically" while the other side says "How many times does this need to happen before you realize 12,000 Americans died from this last year and I don't want my kid to be one of them."
Here's an issue where I think half the side thinks the world is on fire and the other is content - without getting into the merits of either side I do think it's unreasonable for the anti-gun control side to continue to argue against having a discussion for the sake of decorum. This is a divide we need to resolve.
