One should remember the Chelsea District in NYC is a gay district near Greenwich Village. Can you say White Nationalists as possibly responsible? I am not saying definitively but but simply saying generally right WINGnut vicious racists, nationalists, anti-Semitic and homophobic hate that can be responsible too. Do not automatically think ISIS terrorism. We have our own terrorists under the Alt Right Nationalist banner those who enthusiastically support Donald Trump.
Donald Trump's right is as violent, hate infused, racist, sexist and generally vicious as any other group and was responsible for the Oklahoma City bombing, Waco, Texas standoff and many other violent episodes throughout the nation!
