Ah this is so difficult. On one hand, you shouldn't be discriminated against of course. But on another, I'm immune suppressed and wouldn't feel safe around someone without a mask on, so I wouldn't feel safe being in the same place as you. There's been a couple of times I've left somewhere due to non-mask wearers, it's not worth the risk to me. Surely I have the right to be safe too? Just as you have the right to decide not to wear a mask? Or any other face covering?
I avoid indoor leisure where prolonged use of masks is required. I would imagine many people that can't wear them also do the same.
I go shopping when it's quiet. Partly to avoid queues, partly because it's easier to maintain distancing and less likely to encounter aggro.
The school playground is a non-issue as its outside.
A pub is about one minute until seated then masks are not required.
Not being able to wear a mask is legally protected, but I should imagine that many exempt people have adjusted their behaviour compared to what they would otherwise do.
People don't always have compatible needs. DS1's autism means he has different and often incompatible needs to other members of the household. None of us can all neatly arrange our lives to our personal optimum. There will be compromises and clashes of need.
If I choose not to go somewhere because I am not comfortable with the conditions, that is my responsibility and different to being illegally obstructed to going about my lawful business.
It's not an easy situation on anyone.
