One possible response to stupid teacher: "Well, maybe the reason they don't talk is because idiots like you just aren't worth the bother."
One possible more diplomatic response if you feel like being diplomatic: "Excuse me but I do find that offensive. You really shouldn't say things like that about people, because how would you feel if someone has said those things about you?"
Or, there is always the option of complaining to a third party with the power to chastise said stupid teacher.
The trouble is, you can't really fire a relief teacher, because they are essentially only temporarily in the school's employ (for the period of a day, or whatever.)
I suppose the school authorities could, however, always opt for a different relief teacher in the future.
I don't see what the issue is with describing levels of thinking in relation to other levels. Some creatures and individuals are cleverer than others and this should be reflected in the sliding scale of respect that is given to them. People are not all made equal. Some people are just better than others overall.
That really is a very mistaken attitude you have there. That's exactly the kind of idea that would have fitted in perfectly when Hitler had his concentration camps and mass exterminations of anybody he thought inferior. I hope you're only saying these things because you're young and don't know any better yet.
White Anglo-Saxon protestants. . .the entry requirements for the KKK. See, anything to do with wasps are evil!!!
Sheesh. Just because a person fits the criteria for something, doesn't mean they're evil!

I don't start with ideas, I start with things. Then I look at the patterns of things and see how they fit together.
louise quoted....
An ideology is an organized collection of ideas. The word ideology was coined by Count Antoine Destutt de Tracy in the late 18th century to define a "science of ideas." An ideology can be thought of as a comprehensive vision, as a way of looking at things." WIkipedia
Louise - ideas start by looking at things and seeing a pattern, this is how ideas are formed.
A few steps along in the process groups of ideas form ideologies.
I feel you need to listen a bit more Louise - listen and learn.
You are young - I can see you want to explore ideas but to explore ideas you need to listen a bit more to what other people say and consider and explore other ways of looking at things. Don't form your own ideas first. Always be open to new ideas.
And don't be such a condescending prick.
oh - are you suggesting I'm a condescending prick ---oops
A way to test your rigourous core assumptions - is to take on other ideas - and consider. You seem to stick firmly to what you believe is real - you don't seem to be open to others opinions.
You have to start in the abstract. Start with the ideal, and mould the reality to it.
That is the way to form a closed mind.
maybe asking and questioning ideals is a way or process of trying to make sense of our world and working out where we fit in it. Part of learning and working out how we fit into society.
Not sure.
andi have no intention of going into any area of law where my clients are less intelligent than me.
Louise - I am really curious to know how this would fit with a lawyers code of ethics.
Your statement above really makes me wonder about your moral values. 
Anything I missed?
Yes - you seek to join a profession that concerns itself with justice, fairness and equality in society (based on social norms). Yet you say you will only work with people who are of equal intelligence.
How do you equate this attitude with the ethics of law.
I do not abuse anyone. I just don't respect people I am better than.
And I hope someday you find such a person, unlikely as that seems.
... my remarks are not motivated by disability but by stupidity.
And on that, I believe, we can all agree.
Perfectionism can only lead to loathing, in your case self-loathing, in Louise's case loathing of everyone else.
Louise's loathing of everyone else is a cover for her loathing of herself. While her loathing of everyone else is comical, her self-loathing is fully deserved and should be respected. I resolutely stand by her in her loathing of herself, and defend the appropriateness of it. It appears to be one of the very few fully warranted conclusions she's drawn.
It's all a form of intellectual snobbery.
