In my role of Evil Incarnate of Mumsnet, I reviewed my posts and have not seen how I managed to provoke such a crude and emotional outburst from the OP.
I will admit to saying provocative things in the interest of making people think, but none of what I ever say is meant to be taken personally. I pretty much stick to writing about my own decisions and opinions, and never expect people to agree with me. As a teacher, one of the values I have is getting my students to acknowledge other people's points of view even if they don't agree with them - it's an important part of being a scientist. I wonder if I expect too much from adults?
Anyways, as far as entitlement is concerned:
I do think that children are entitled to an education free from disruption, and I think they have the responsibility to not disrupt. In turn, parents have to nurture good values in their children so that they will not disrupt.
IME, disruption, mostly low-level, is the biggest problem facing education at the moment. In independent schools, they are not immune but tend to deal effectively with disruption. Unfortunately, many state schools do not have effective procedures, and do not have the ultimate power to expel.
These problems are endemic in schools, and IMO are due to poor parenting, right from the earliest ages. I think primary schools do a good job at keeping a lid on it, with their effective pastoral care (ie a classroom teacher who really knows the children because of their large amount of contact). It is so hard when they transfer to secondary and become an unknown with no one really looking out for them until they become known to staff for all the wrong reasons.
Disruptive behaviour is what has convicted us that private schools are the right place for our children. Yes, we have the choice that is not open to everyone, but it is still a choice that we do have and we cannot un-invent that choice - the genie is out of the lamp. We have decided to exercise this choice rather than frittering away our money on material things. It would be very wrong for us to have made alternative choices just because others don't have the same choices.
We did not get to this place by accident - we did it through education, hard work, and time (we paid our first set of school fees in 2003, having graduated in 1986). We are also fortunate to have a modest house that we are content with.
