ok can i ask a pretty simple question?
mayb i am wrong but i do not know of anywhere on the torah taht it says jeans are asur…but it does say vahavta lereacha komocha and im pretty sure that it does not specify whether they are wearing jeans or not…so i believe we should stop jusdging someone because they are wearing jeans and if they want to do it let them and dont change your opinion of them
and as an aside…do the gedolinm get to say about things not directly related to halcha but more of how one personally lives their life…even if it is not written in the torah or gemara?
