Also in terms of it going both ways
Two months ago I was on a train. It was absolutely packed because the one before had cancelled.
I have disabilities which means not sitting down is agonising for me, but the people in the priority seats all looked in clear need of them and it was the kind of busy where you just get pushed down the carriage by the people behind you.
So I ended up standing up squashed between the people in front and behind me in line with the table seats either side
I ended up having an asthma attack, unrelated to the circumstances, I just have bad asthma and I was having a bad week with it. But it was bad, bad enough that I was trying to work out if I needed to call and ambulance to meet me at the next station bad.
The young woman behind me had to get my inhaler out of my bag because we were so tightly packed I couldn't take it off. Then bless her she started asking around in a loud voice if anyone could spare a seat for me
On both sides of the table seats were parents of fairly young children, probably 3 or 4 year olds on one side and maybe 6 year old on the other side. Neither offered to put their child onto their lap so that I could sit down, they both just totally ignored the situation. It was actually a lovely teenage lad travelling with his friends in the seat back from where I was standing who gave it up, after some complicated mananouvers to make enough room for him to stand up and me to get back past.
So no all of this 'people should have consideration for those with greater needs' doesn't always go both ways
Obviously many parents are lovely but let's not act like it's just women without children who are going round ignoring other people's needs
