Religious dress codes are highly primitive and alienating philosophies. Religions also should evolve to a better one over a period of time.
Different religions advocate different dress codes for the members. For example Sikhs are required to wear turbans and long beards; Muslim men beards and caps, Muslim women burka and Hindus cross thread over the chest and ash or vermilion marks on the fore head. This leads to immediate alienation from one another. Let us all roam in the streets as human beings and not as Hindus, Christians, Muslims and Sikhs. This is not civilization.
