I’ll accept no lectures about “sensitivity” on days of tragedy like today from people who work the other 364 days of the year against any attempt to prevent such tragedies.

It’s bad enough to have a gun lobby. It’s the last straw when that lobby also sets up itself as the civility police. It may not be politically possible to do anything about the prevalence of weapons of mass murder. But it damn well ought to be possible to complain about them - and about the people who condone them.
