The murder of the abortion doctor is murder. It is wrong. No matter how you slice it.
Abortion is legal in this country. If you want the law changed, then lobby to have it changed. If you want to restrict (or prohibit) the use of tax dollars to abortion clinics then lobby for your point of view.
But if the only tactic you have to make your point of view is the taking of a life (the life of the abortion doctor) then you are no different than bin Laden.
If you don't like the procedure, don't have one.
But if the only tactic you have to maintain your sexual promiscuity is the taking of a life (the life of the unborn child) then you are no different than bin Laden.
If you don't like the procedure, don't have one.
If you don't like "the institution," don't own slaves.
If you don't like "the resettlement facilities," don't volunteer for the SS.
If you don't like "the ethnic cleansing," don't work for Slobodan Milosevich.
If you don't like "the collateral damage incurred during a strike against the infidel's power centers," don't support al-Qaeda.
(Just thought you'd like a few more for your list.)
Killing is wrong, period. Saying "If you don't like 'the procedure' [sic], don't have one" is a worthless throwaway line.
