MJ, that certainly is your opinion and you are entitled to it, but I tend to distinguish between a stereotype and statistical data. It is one thing to be politically correct, but when it comes to spending money, expecting more safety and many other practical aspects, people rely on statistics to find out what is more likely to happen or typically (normally) happens in each case.

For example an insurance company has studied the statistical data concerning the drivers involved in accidents and notices this huge group of drivers that have had the most accidents:

16-year-old girls were involved in 175.19 motor vehicles crashes per 1,000 licensed drivers in 2000. 16-year-old boys were involved in 210.3 motor vehicles crashes per 1,000 licensed drivers in 2000. That's total of 385.49, which means that 16-year-olds have been involved in 39% of accidents happened in the year 2000.

So they charge a 16-year-old male driving a red car a higher premium than any other driver, simply because it has been a normal and typical behavior for people of this age, sex and choice of car to be involved in an accident. A certain 16-year-old male driver might never be involved in an accident for as long as he drives and that could be many years; yet if you are the one who is supposed to insure him, you would not take this risk to insure him with a lower premium.

Another example: When a Middle Eastern goes through check points in an small American airport that has the policy of random searching the luggage of suspicious passengers, his/her bags is the one that will be searched over that of an American, simply because the statistics are not in favor of the Middle Easterns.

Again, a normal attribute, is the attribute of majority of members in each "set". A normal attribute is not necessarily the good, or the bad attribute. It only reflects what is more likely to be expected when you encounter one of the members of that set. Of course there is always this chance that what you've expected would not happen. You could encounter an exceptional member of the mentioned set, yet it is always better to be safe than sorry.

The same goes for aggressiveness in boys and girls. Simply because the majority of boys are aggressive, the chance of a certain male being aggressive is higher. This doesn't mean that there are not boys who aren't aggressive. For Kris's son, what has been expected has happened. For someone else's kids there is a small chance that this does not happen.
