Either everybody on this thread is under fifty years of age or they’ve really got amnesia. Fifty years ago Jews were actively discriminated against in the USA, and it was worse for Orthodox. It was really difficult for a shomer Shabbos person to get a job, and you could be fired for wearing your yarmulkeh or sheitel to work.
A lot of Jews who had been brought up Orthodox went frei because the employers said, “If you don’t come in on Saturday, don’t come in on Monday.”
Many title deeds in white neighborhoods specified that the house could not be sold to either a black or a Jew.
That’s why so many Jews participated in the Civil Rights Movement. If you check the Civil Rights Act of 1964 it forbids discriminating by religion as well as race.
So remember that discrimination isn’t just about *them* – it’s nogeia b’davar for us too. Most people who don’t like blacks don’t like Jews either, they’re just a little more careful about expressing it. Same for discriminating against gays. We don’t hold by their activities, but the same kind of prejudice can get redistributed back onto us if the social climate changes. Better to be against all social discrimination on the public level, and maintain our own standards in our own communities.
