OL~
I have to take exception to some of your observations.
First~ "I think that all this, all the parents, all the worries, all the frets, and all the, "My kid needs to be fixed." mentality boils down to pure hatred." I have fretted, worried, and believed that my child needs some "fixing" (her thinking processes can be very skewed). For example, her thinking that because she doesn't' look like Kate Moss or Paris Hilton, she is ugly and not of great worth is wrong thinking. These types of thought processes require "fixing", or at very least consideration. Of course I worry about my daughter. I love her and I want her to be happy and find contentment in life. It is the furthest thing from pure hatred. Hitler exhibited pure hatred for any person not of Aryan descent.
Secondly~ You seem to not understand the idea of detachment. Or tough love for that matter. Allowing my child the dignity to make her own decisions, and then allowing those choices to bring whatever rewards or consequences is (IMHO) detachment. If she chooses to do drugs again, and gets caught,gets arrested and is incarcerated by the juvenile system, that is her choice. That does not mean that I don't love her, or grieve over here consequences with her; it simply means that I will not bail her out of her painful consequences (and of course there are exceptions). I am not trying to force her to her lowest level so that she will crawling back and submit to me. I am allowing her the freedom to make her own choices and to learn by them.
I have always told my kids that there is nothing that they can do that will make me love them any more. AND, there is nothing that they can ever do that will make me love them any less. I love them because they are who they are, not because of what they do or don't do.
You are young (not said in a condescending manner mind you). You have not parented. And while you bring many good points to the discussion, until you parent, your perspective is that of a non-parent. But, do not assume that all parents who practice detachment are motivated by pure hatred. Some are actually motivated by pure love......
