Popa, 2 things.
1)Please explain how I missed the point. Don’t try to justify stupid (yes, stupid) chumros that never existed in yiddishkeit by comparing it to other ‘weird’ halachos that are issurai d’orayso. We follow mitzvos because that is what hashem told us to do. No questions asked. So some mitzvos may seem funny or outdated but we do them anyway. That doesn’t mean you can extrapolate that to cover every idea that pops into your head. If it was so important for women to walk on separate sides of the street, I think the tannaim and amoraim would have covered the issue.
2) I don’t know if you are trying to be funny with your subtitle (mildly retarded) but it is extremely offensive to parents and family members with retarded children.
