But if I must..basically they teach the lefty view of things on this BBS, not mine.
I must stress that those lefty views could be considered in the middle somewhere.
Your list is your post's own worst enemy - I'd have a lot more sympathy if the average high school syllabus covered even half the items with the bias you state. Or more than just the part about sex... the other stuff is just a big laundry list of your grievances against people to the left of, or more liberal than you.
In real life, not BBS arguing, I'm probably considered a pretty conservative person. I'm white, married, earn enough to be taxed at NZ's top tax rate. I was private school educated, went to university and did pst grad in Finance. I work in the finance industry and go to (Catholic) church every week, plus help organise a young adults group and am involved in other youth ministry. I agree wholeheartedly with the vast majority of the Church's teachings.
I favour free markets where possible, and want the lowest, flattest tax rate that is feasible - I ask only for a safety net for those who either cannot, or will not, look after themselves in the way I would. I recognise that I have been dealt a good hand in life, and I can't condemn those who haven't. Yeah, I think corporates need to be controlled, that progressive tax systems are required, and
this one will surprise 
I think that government wastage is a necessary evil. I see it as an inevitable outcome of central control - something that can only be managed but not eliminated. Corporates have their own wastage ... govts are not alone.
But most of all, I believe in people. I believe the average person wants a better world and that we can all work together to achieve it. I DO NOT believe that society should give up on anyone. I especially do not believe that all people are going to help themselves when things are bad --> it's a strange mix of optimism and pessimism.
I am consistently amazed by how far to the right you sit from this. Plus, I am always a little amazed at your apparent disregard for those who would suffer from your schemes. To put it briefly, why don't you care about what happens to them?
