(NC'd but old hand here)
DH tends to chat in various discussion groups, and yesterday, in a discussion about roads told someone to fuck off.
Here's the conversation which started around using buses and how everyone should do it to relieve road congestion,
DH:
And wheelchair users can wait all day, and still not get a bus if there are people refusing to move their baby buggies.
POSTER:
What are parents to do if they have a child in a buggy, some shopping
underneath, so it cannot be folded and cannot relinquish their position and get a later bus, because they have to be at school for a particular time to pick up their 5 year-old child?
DH:
That's choice, compared to the necessity to use a wheelchair.
POSTER:
It's not choice if you have to do the shopping so as to have an evening meal, have a young child that you have to bring with you and need to pick up the other child from school. The wheelchair user may well have much more choice, as many can walk short distances and chairs
can fold. In some cases, their journey may be purely frivolous, unlike the example parent.
It was at this point DH suggested the poster "Go f* themselves".
I should add that obviously DH is sensitive to wheelchair users (which is what I am) and tries to be polite where he can (as befits his age, and maturity). But he's fretting now whether he was too abrupt 
.
I wonder what the vipers of AIBU think ? (For the record, I am 100% on his side, here ...)
