rabbiner, the choson/kalla also hold hands at the mitzvah tantz and after the chupa. do you hold your wifes hands in public? If you do, there is nothing left for us to talk about.
insuranceguy, I’m sorry to hear that you are ashamed to be frum and duck under your desk everytime you see someone with a yarlmulka passing by. If thats what embarrasses you and (or if you think thats what breeds anti-semitism) you need to stop being a caveman, come out and breath the fresh air.
