Yes, I do agree with you entirely.
However, he said that private schools are where "berks send their children there by a nanny in a Range Rover, and spend ludicrous sums of money to do so because they are above everyone else".
That is a direct personal attack on ALL people who attended one as he didn't state "where some berks and other hardworking people".
Obviously I couldn't give a flying fart what he thinks as he seems like the sort of person you'd expect to see in skaggy tracky bottoms and no shirt, having a BBQ on his front lawn stood next to his rusty sierra with a tarpaulin over the rear window, but I felt that I had to put him straight as people like him need educating in these little "life lessons" or they just carry on thinking they know it all (when usually they know very little).
