Roz didn't say that. In fact I specifically didn't and don't believe that the rights- of my children not I- trump those of wheelchair users but with a double buggy I would have to, like a lot of people, make a judgement on whether it is appropriate or practical for me to take them all off the bus- also having paid a fare- ( however I do appreciate that my three children with their free travel and cumbersome carriages are clearly leeches on the rest of society).
I also never suggested that they all get off to allow us on- just to shift along peacefully to permit my children to access the designated buggy/wheelchair space.
