And there are people who are brain dead morons still wearing them for no other reason than they're brain-dead morons. I know a lady suffering from cancer and she wears one in public places. I get that. I also know a lady who is perfectly healthy and wears one everywhere, including alone in her car. She just wears it. No logical reason. She even pulls it down all the time to talk. What's the point ?
Why do you care? Really? This seems to really bother you. Are they trying to strap one on you?
Go for a walk and lighten up. You are not the boss of people. It’s what liberty is all about.
