SJS- what’s eating you? Why are you so against it? It’s one thing to say you don’t HAVE to wear it, but another to dafka dislike and be against yeshivish/chassidish livush.
I would understand your position if you told me the yeshivish guy at the zoo was wearing his black hat & jacket and was acting inappropriately. Then I can hear your argument about what is & what isn’t important. But to despise the livush in and of itself simply boggles the mind.
