One of the most annoying things about Orthodox Jewry is the fact that it is common that the men wear Black Hats. The Black Hat is considered by many a statement of Orthodoxy. To them the hat is like THE ultimate in Jewish clothing. To many the concept of perpetually replicating an Oreo cookie by way of dress is somehow holy. Supposedly, the story goes, the black and white with the Abe Lincoln look-a-like hat, is "Jewish."
Aside from the fact that the hat is ridiculously unattractive on most people, the hat is not at all Jewish. The hat was a customary article of clothing in many Eastern and Western European countries. Meaning, the Jew were NOT the only ones who wore hats. ALL the people wore them. Some people left the mid-ages behind, and the hat just represents that Jews are backwards.
Regardless...the biggest pet-peeve of all is when a sephardi guy wears a black hat. At least Ashkenazie Jews have an excuse as to why they're stupid (it was part of goyish culture), but many of the Sephardim of middle-eastern and Asian background have absolutely NO trace whatsoever of black-hat wearing in their past.
A few of my Sephardi friends hate the fact that on dates, guys wear hats. They hate it. It absolutely bothers them that this new wave of yeshiva returners come back "frummer" than their fathers by turning Ashkenazie.
Whatever...I think ALL men should abstain from wearing such atrocities on their heads. They're ugly and expensive and impractical. If you really want to wear "Jewish" clothing, put on a pair of knickers and turban, and sandals, and viola. Until then SHUT UP, its NOT Jewish clothing you damned GOY!
