If this is Fall River Massachusetts, then I have to wonder if it even happened. I seriously doubt that there are actual neo-nazis in Massachusetts. More likely, this was a group of ordinary conservative citizens, and no nazi slogans or symbols were ever in evidence. But more likely than that, the whole incident is fabricated; wishful Leftist thinking and a way to slander conservatives.
I say there is a good chance that the “neo-nazi protesters” were likely to be drag queens who were not wearing drag. They probably took off their tutus, dressed up as “Trump supporters” and put on a little show outside the library.
And, by the way, I worked in MA libraries for a very long time. Librarians, in general, are far Left of Stalin. And the percentage of homosexual librarians is off the charts. These are radical rabble-rousers who would do anything to make Conservatives look bad.
Leftists lie.
