Dozens of lives lost.

Unfortunate but 'chump change' compared to the ongoing slaughter by right-wing extremists.

Like the people killed by right wing extremists with Assault rifles

... and run down by Nazi in cars

...Or the police shot by anti-government right wingers in Oakland and Santa Cruz during protests (killers were active military guys)?

.... Or TimMcVeigh, the neo-nazi who blew up a building in Oklahoma killing 168 people, injuring >600....

....or the neo nazis who slaughtered 2 cops in a Vegas pizza store, placing swastikas and Gadsden flags on their lifeless bodies?

...or the clinics bombed and doctors killed by anti-abortion bible-thumpers?

..or the churches and temples shot up by right-wing racists?

...or the soaring attacks on Latinos, Asians and Pacific Islanders in the wake of Trump's racist diatribes?

Yes, right wing extremists.

Anti-zionist/pro-pal demonstrations do not negate the horrific impact of vicious right wing slaughters.

Right wing extremist violence remains the dominant form of domestic terrorism.
