Conservatives are angry as Hell about the London attack, but totally calm about the recent Orlando attack, despite the fact the death count is roughly the same.
I doubt the relatives of the London victims feel reassured that the victims died at the hands of a terrorist, rather than at the hands of a disgruntled worker.
Conservatives are eager to come forward with ideas how to stop terrorists. Not so quick to confront random gun violence with no non-Christian terrorist angle.
