Really really praying for the #TreeofLife community in #Pittsburgh. Squirrel Hill is my old hood and the Jewish community has always been welcoming to me from Brooklyn to Miami to Pittsburgh. Jesus Christ, help us all. America is sick.— Wild 🐝 Slaying 🐉 (@glowbug28) October 27, 2018
A lot of Twitterians instantly called for government action to tackle both mass shootings and anti-Semitism.

I am OUTRAGED. This is my hometown synagogue. Too many guns! Too much racism! Too much hate speech! It’s time for our country’s leaders to take responsibility for their rhetoric & take action.
