What a stupid comparison.
One could say the same about the 9-11 attacks, or the mass killing of Sri Lankan Christians, or for that matter a deadly attack on your own family by thugs with hammers.
All are examples of grievous tragedies, not entrants into some sweepstakes of death.
Falling into a meat grinder is a horrible, very rare accident. The toll of terrorist acts is small compared to the systematic, state approved killing of innocents inside the womb every day. 42 million abortions are carried out annually worldwide with about 650,000 in the US.
The regularized, legal murder of human life is far more insidious and horrible than the examples you cite. And it rarely makes the news.
