Everyone is invited to read the sefer in English called
“Rite (Minhag) and Reason”
It’s a sefer filled with hundreds of all the minhagim in klal yisroel and the reason behind each one. If you read it then you will clearly know that nothing was just made up or stupid or because a Rebba just decided to do it etc…..
Then you won’t have any more questions on the minhagim in klal yisroel no matter what kind of yid you are from Aschkenaz to Syrian Jews as Sefardim to Israelis etc…..
