One of the many fine organizations I’ve worked with over the years is the Jewish Labor Committee (JLC), an organization, founded in the 1930s by Jewish Labor activists, to combat the rise of Fascism at that time.
Now the JLC is still in the fight against the current crop of Fascists. They are helping to circulate a petition to combat hate just as was seen in Charlottesville this past weekend. Here is the link, https://actionnetwork.org/petitions/never-again-means-never-again?source=direct_link&, I urge you to sign it. Thanks.
