Many twitterians were infuriated as they learned that the assailant had shouted "all Jews need to die." They pointed out that anti-Semitism doesn't seem to have been wiped out in society.
"All these Jews need to die," gunman shouts at police on scene at #Pittsburgh synagogue shooting. Anti-Semitism alive and kicking, the epitome of evil.

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.

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. NOW. @USJewishDems @ChrisMurphyCT @MomsDemand #Pittsburghshooting #pittsburgh https://t.co/MwKgJDFTQc
