and call people who don’t “trashy”, and look down on them- which you do. (And be ???? on baal tosif by pretending it is halacha)
Popa, that is a very important point. By pretending it’s halacha they commit bal tosif. By looking down on people who don’t keep this “halacha” they are m’galeh da’as that this shita supercedes other, real, halachos. That’s what I was talking about when I posted earlier that it’s sometimes a mitzva d’oraisa to wear jeans. The exact lashon can be found in Devarim 7:5.
