Well debating, is debating. It's not age specific. If you can't bare to have your points challenged maybe think them through more thoroughly.
The point in question was WHY is it immoral, or wrong.
I think you've just proved the point I was trying to make whereby you state capital punishment is immoral whearas that is an issue that society is still relatively devided over, in general terms we as brits believe it is immoral whereas many states in the US believe the opposite.
Basically your argument is that your understanding of moral behaviour is whatever standard YOU deem to be correct because everyone should think like you?
Therefore if true then everything that is moral and good is whatever I deem to be moral and good also.
Can you see how this could become a problem?
If youre summising that everybody should just know because they're human that's a silly argument. If that was the case there'd be no need for laws or punishment.
