“The requirements that the knees be covered at all times in public…. isn’t anyone’s “vision of Tznius”; it is an absolute obligation.”
Actually it is someone’s vision, and a distorted one at that, in multiple cases we have read about in recent years, including here on YWN, where misguided zealots endow themselves with enforcement authority and have physically and verbally abused women who most of us would agree are meeting commonly accepted tzinius standards based on their vision of a more rigorous standard. Most frum women actually go beyond the minimum standard and when visiting another community with more rigorous standards, seek to conform with “minhag hamokom”. For some, that may not be enough. Harassment of even young girls standing outside of a BY or walking in the park by these self-appointed tzinius vigilantes are becoming all too common .
