Again with the silly, hyperbolic extrapolations.
Your arguments are based on emotional reactions, not logical reasoning. You have repeatedly failed to give any sort of answer as to why, whatever the reason someone else wears pyjamas outside of the house, it makes the smallest difference to your life.
Why are you bothered about someone else wearing muddy slippers in THEIR house? It's not your carpet.
Why are you bothered about someone else's child being embarrassed?
Why are you bothered about someone else getting back into bed in pyjamas worn outside? They aren't getting into YOUR bed.
None of this has anything to do with politics or even disability, etc. it's about why you think it is your damn business what someone else wears. And not once have you come up with a single logical reason as to why something you don't do, and nobody is making you do causes you a problem.
You have given us lots of reasons why you think it is a problem for the people who do it. But that isn't your argument to make. That isn't for you to decide. Just as it isn't for me to decide why you wear what you wear.
You don't want to wear pyjamas outside the house. Fine. Don't wear them. Problem solved for you, isn't it?
I manage to not wear pyjamas outside the house without making a big song and dance about it. I don't give two hoots if someone else wears them to go shopping in. Why would I? It's not affecting the price of my groceries, it's not making the bananas shrivel, it's not causing the ice cream to melt. It's no more of a health hazard than any other fully clothed person presents in the supermarket.
