What if my wife is a member of the 'religion of peace' and wearing her hajib wants to make a large cash deposit at my bank? Seems like that is defined by statute as a 'mask', but it conflicts with my 1A rights....
Your 1A rights are not in play, so step out of the picture.
If your wife is wearing a "hajib"
http://en.wikipedia.org/wiki/Hajib she has committed so many violations of the strictures of the Religion of Peace that getting into a bank will be the least of her problems.
Now if you meant "hijab"
http://en.wikipedia.org/wiki/Hijab and had bothered to read your case law you would know that her 1A rights are not effected.
IT is is impossible for a bank to violate your wife's 1A rights - or those of anybody else! It takes a government to violate constitutional rights.
Further, if you read your case law you will find that the wearing of a hijab is
not considered the wearing a mask - although your bank may be blissfully unaware of that.
Your argument would have been better made if she were wearing a "surgical" mask either because she had a comunicable disease[SUP]1[/SUP] and did not want to infect others, or if she had a compromised immune system and wore the mask to prevent being infected[SUP]2[/SUP].
stay safe.
[SUP]1[/SUP] - folks with active airborne communicable diseases which might otherwise get them quarantined have been allowed to walk among us so long as they wear a mask.
[SUP]2[/SUP] - Think cancer or AIDS especially.
