I don't know about you, but I don't think I have ever needed to defend myself against anyone. That's one of the perks with living in a civilized country, ruled by decency and common sense (at least most of the time).
Liberals love FREEDOM, stupid. The freedom to decide what happens to your own body, how and when to have children, whom to love and (perhaps) marry, what to believe, what to say, etc.
I'm no liberal, I'm a socialist, but still; the very thought about ending the life of a fellow human being disgusts me. The only justified killing, in my mind, is euthanasia; when someone is dying and in unbearable pain, and wants it to end, but can't do it him- or herself. A fetus is not yet a human being, and the life of the woman trumps that of the potential life of the fetus.
Mass murderers and serial killers are sociopaths, they don't really care about freedoms.
