snappity I, as a female bodied person, can absolutely understand why the airline may need me to swap seats with my male bodied person fellow traveller due to safeguarding issues.
I'm not expecting to be a free 'nursemaid' (interesting phraseology you use there, cos, they aren't toddlers on this type of flight arrangement)
And, you know, quite a lot of us parents have experienced flights with kids. This is really not 'classic feminism' grounds. This is 'classic humanism' grounds for behaviours. Flights in airplanes force us all into small spaces which demand stronger humanity than normal small spaces, otherwise shit falls apart.
And all the children I've ever encountered on unaccompanied minors-type flights tend to the sort who don't need 'free childcare' as their parents have nurtured and raised them to be independent and confident children who are OK to go on flights on their own, regardless of the complex reasons they may need to be on that flight.
The more you post, the more I don't think you understand about parents/kids.
But I'm sure you'll tell me why you do!
