All of my dc went to state schools, from Reception through to Sixth form, @BonnuitMy. One has a law degree and a good career in quantity surveying. The second has a degree in Applied Maths and a PGCE, and is a high school maths teacher. The third has a degree in Geography and a good job in sales. I fail to see how them having to go to state schools was a ‘misfortune’.
And I don’t think people are saying you are ‘buying privilege’ by having second thoughts about a play date - they think you are buying privilege by paying for private education for your child (if, indeed, you are doing so - it isn’t clear to me).
But my question is similar to the one others have asked - why do you have to agree with the parent’s political views before you will agree to a play date? Surely you can either avoid political topics, or, if the subject does come up, put forward your opinion, politely and non-judgementally.
I have friends who don’t share all the same political opinions as I do - hell, my dh has different political leanings to me - but generally we can discuss them politely and respectfully, listen to each other’s opinions, and agree to differ without falling out.
