The dominant trait that drives the modern conservative is a bitter, unhinged hatred of all things liberal. So unhinged is this hatred that the mass shootings themselves aren't the problem, rather it's the push by liberals for legislative action in response.

Universal background checks or restrictions on automatic weapons? Nope because they wouldn't have prevented the Vegas killings. If it can't be proven that any new law or regulation would have prevented Vegas or Sandyhook or Orlando etc etc then the conservative is dead set against it. 

Since you've blocked every proposed solution for the last 25 years, this is on you, conservatives. Let's hear your solutions. And remember conservatives, by your own standards, every proposed idea must guarantee that it would have prevented Vegas...so don't bother with the "if only more citizens were armed" thing.
