This Shabbos, I was 0-for-2 in private discussions I had in shul following davening. Before I addressed a bar mitzvah boy, I opened with the following question to the audience: Imagine if David Duke, of KKK fame, succeeded in becoming a Republican congressman, G-d forbid. He then decides to visit South Africa. The South African government rejects his entry on the basis that he is a notorious hate-filled racist. Would anybody in the world have a problem with the decision of that country to keep that harmful person out? Would Republican colleagues have rallied behind him? Would there have been a threat to our bipartisan relationship with South Africa? The answers are obvious, as is the point. I did not need to spell out what I was driving at.
