No, it's just like I said, you can tell a liberal by their willingness to break all the rules for the sake of one person rather then change the rules for the sake of all concerned.
If you believe that every other family in this case, every other child in this case, that has obeyed the rules doesn't count and that this one "family" and this one child that disobeyed the rules does then you are a liberal.
This "family" has no respect for others since they decided that the rules the others are living by don't apply to them.
That is liberalism in a nutshell, rules are made to controll the other guy.
I have no problem with the expulsion. A private school can do as it wishes.
