I think wearing masks is like what smoking in public establishments used to be. "I hear that it may cause harm to others, but I don't believe it, and what I want is more important anyway.....so deal with it."
I view wearing a mask a common courtesy to others so I do so when I'm in public. I've had occasions where I didn't have a mask (was in my other vehicle) so I just did what I needed to do without a mask. I believe wearning a mask makes a positive difference.
I was watching the news tonight where some city somewhere adopted an ordinance requiring masks and a woman was complaining about her constitutional rights being violated... I suppose she hasn't really read the constitution lately or has forgot what is says.
