A friend once asked me what kind of kippah I’m looking for when it comes to shidduchim. "It doesn't really matter to me," I replied.
"Really?" she asked. "What if he wore a black velvet kippah? What about kippah sruga? What about a black hat? A big white kippah?"
"As long as he wears a kippah, and we have the same values, that's what's important." I answered honestly.
Different head coverings for men (and women who are married, but that’s a different story) are just ways for Jews to separate themselves from other Jews. It adds to the judgmental mentality and increases negative feelings towards one another. "Oh, he wears *that* kind of kippah. Tsk, tsk. That's not my type of Jew. I don’t associate with those types."
I think that all Rabbis/ Gedolim of all movements, denominations, whatever (Chassidish, Yeshivish, Modern Orthodox, Conservative, Conservadox, etc, whatever you want to call all those categories)- all Jews, should get together and pick one type and color of kippah, and declare that all Jews should wear it, as an attempt to avoid Sinas Chinam.
The main opposition to this idea would be: Which kippah do you pick? If you pick black velvet, those who wear kippah srugah or are prejudice against chareidim will refuse. If you pick a kippah sruga, the black velvet wearers would never agree. And picking one of those colorful conservative type kippahs that stand up on guys heads like a triangle, well, those just looks odd.
I was thinking maybe white velvet would work- kind of a combination. The main problem with this is that those who wear black hats will still want to wear black hats, and those who don't wear hats at all will not want to wear hats, so that will create division. And people wouldn't go for the white velvet idea because someone will claim that it is "against tradition" and put a ban on it.
Perhaps this wouldn’t solve anything, as those who are determined to be prejudice would find other ways to be discriminatory. Perhaps those wearing jeans or colored shirts would labeled by some as “modern”, and those in white shirt black pants would be labeled by others as “frummies.” But at least everyone wearing the same kippah would be a step in the right direction. It would facilitate the realization that, “Maybe this person doesn’t keep Torah in the same way I do, but we wear the same kippah, there is something the same about us, we are all part of Klal Yisrael.”
