Because science.
edit: after reading so many thoughtful comments, I am changing my view on this matter. If you are sick, and go out in public, please be kind and don't spread your germs everywhere. If this means wearing a mask for you, then God bless you. If you choose for whatever reason to not wear a mask, then God bless you and you should be free to decide that. If you go out in public, you assume risks that there are germs out there. If you are not comfortable with those risks, you have the right to no go out. If you are a business, you should not be required to put up any signs or enforce any such orders. In fact, there shouldn't even be such orders. In other words, let's just go back to the way things were. This may mean imposing a BAN on requiring masks not a ban on the masks themselves. Thanks all for the lively discussion.
No. There should be a choice. If anyone feels safer wearing a mask. Go ahead but do not attack others for not wearing a mask.
I’m going to have to disagree with you on this point, fren.
Why ban masks? The mandates on masks should stop. Maybe some consider it a fashion choice now.
Wouldn't that be funny - if people started wearing masks to avoid such detections!
In a free country, there is no reason to create laws to restrict a person's personal choice if it does no harm to anyone else. Masks do work to a limited degree if you are very sick and want to go to the grocery store while reducing the chance you'll make someone else sick. Otherwise, we all need fresh air to stay healthy.
