Authority is a damper on freedom that is a necessary evil because of the evil of humanity. It has nothing to do with freedom, except that it guarantees that our freedom will be constrained such that it doesn't interfere with others.
In the process, being wielded by flawed men, it also takes away our freedom for no reason other than power, stupidity, or sheer lazyness.
It's easier for example to simply ban 18-year-olds from drinking, than to teach them responsible drinking and vigorously enforce the laws preventing minors from getting alcohol. And it's easier to ban me from growing pot in my back yard than to police the smoking of that weed, even though the pot in my back yard harms nobody.
Once you give government authority to restrict your freedom, it is imperative to put in power people who find the use of it abhorent. Those who enjoy using their power over people, like Rudy, will inevitably take away your freedoms for no reason because they are lazy, power-mad, or stupid.
Like banning guns because it's easier than policing their use, or banning ferrets because, well, I haven't figured out year why Rudy was upset with ferrets, maybe he just didn't like them and, being power-hungry, figured if he didnt like them then he was mayor and nobody could have them in "his city".
Anybody bothered by the "his city", and "his auditorium" stuff? Sure, he kicked out Afafat so we were all "happy", but what if some really strongly opinionated pro-life person was showing up and Rudy didn't like HIM and kicked him out of "my auditorium". Wouldn't you then wonder how something paid for by all the taxpayers of the city became "Rudy's"?
Basically the same thing that Rudy said, except that since you sad it, it sounds better to you.
Your freedom will be taken from you much faster in a place where LAWFUL AUTHORITY (Rudy's words) is not a recognized concept, than in a place where LAWFUL AUTHORITY is granted, at the consent of the governed, to act as a damper on unchecked freedom/behavior/actions of the population at large (anarchy).
"Those who enjoy using their power over people, like Rudy, "
hehehe...
Now, you ask whether Giuliani is a good candidate or not...
The Office of The President heads the Executive Branch of our government, the branch whose primary functions are to defend the nation, and to enforce our laws.
I believe that he will carry the war on Islamic terrorism to them, and he has shown not only willingness, but effectiveness in the enforcement of laws.
So yes, I think that he is a good candidate for the Office of the President.
