Nin in certain cases someone may have to leave if the situation is intolerable for one party, but that's the same for any issue a person may have where it is difficult for them in situations involving the general public in close proximity.
My point has always been that there shouldn't be blame or shame. Every person deserves to be accepted for who they are. If they have weight to lose, if they have sensory issues, whoever and whatever they are should be 'ok'.
If there is a conflict of interests there is absolutely no point in complaining, it will happen, we are all humans. No need for finger pointing, trying to find which party is 'guilty'.
I don't belong to either the overweight or the sensory issues category but I do know that whoever or whatever someone is is alright with me. I would hope for similar compassion if I were ever to be in a position where I might not always be easy to sit next to, should that ever arise. None of us know what the future holds with regards to illnesses or mental health issues. It's just about consideration for one another, even if a person is making things a bit uncomfortable for me, and if they can't help it and are doing no real harm to me and mine, I can manage with it.
It's not about saying Zonkin is being nasty at all, it's just asking for a kinder approach. There is no black or white in these issues, they are far more complex than 'right or wrong' so let's practice tolerance?
