I tend to be of the belief that kids are definitely not open minded, rather closed minded albeit on different tracks to what we think.
Kids tend to be of black and white thinking and often do not have the capacity to see shades of gray. Their thinking often tends to be aligned with their peer group and any dissidence within it is generally not tolerated.
They toe the party lines because many of them have no wish to be disconnected from or ridiculed by their peers.
I am not saying this is true of all of them, just generalising. There are those brave few who are prepared to step over those lines and will stand up and be counted.
I am also saying this is not a judgement of them, just that most of them lack life experiences and shades of gray do not fit in with their way of thinking. It is something we learn as we go along and learn that people do not really fit into tidy little files and descriptions. A lot of senior folks have already learned this (if they are of a type who have awareness of life), but many of us dismiss it thinking they are getting a bit senile as time goes on... It really says that life is a constant learning experience. A lot of others have also ventured through life with closed minds as well. So we are not all of a high level of awareness.
As an example I can remember telling my aunt when I was about 10, that all old folks over 60 should be put down. All, except, of course, my favourite aunt. She reminded me of this when I was about 23. Man, I was so embarrassed about it. But I was also very young and had no other frames of reference to call upon to realise that my thinking was seriously flawed.
As I approach 60 myself, I think I now have a viable counter argument for that one....
It is also good that kids are saying things, it shows they are thinking and participating in the world. Given time, many of them will modify and temper the way they think. Part of growing up, I think.
As long as they don't go into politics. Then they'll never grow up!
Also Scientology (and celebrity status) will fuck up their ability to think properly big time.
