I oppose any laws about what people can wear on their face.
In Japan it is common for people with cold/flu to wear sanitary masks in public, esp on trains.
We might be wise to adopt that practice too.

Sandstorms are another reason some might cover their face.

In winter we wear balaclavas and scarves over our faces

When it's really cold, wear a face mask or a scarf over your mouth to warm the air you breathe and protect your face.

It used to be common for grieving widows to wear a veil, and is still in some cultures.

A bandana soaked in vinegar is desirable for protests where tear gas may be used

Some protesters are packing their bags with vinegar-soaked bandanas, ear plugs and gas masks, getting ready for any police violence they might encounter.
And good grief ... what about big sunglasses and hats pulled down low/collars up high - the classic celeb. 'disguise'!

Next thing you know, the cops will be measuring your sunglasses to see if they are too big, and high collars and hat brims will be outlawed.
Truth is ... this whole kerfuffle about 'veils' is ridiculous and purely racist.
You cannot have one law for Muslim women and another for children wearing scarves in winter to prevent frostbite, or people trying to avoid spreading germs.
I say ... get over it!
