What is the rationale of those who want to make self defence illegal?

I get how a liberal could want social programs, since it's basically more money for them taken from someone else: Immoral but understood, more resources for your, less for someone else. But why is the first reaction of liberals in an altercation to criticise the person reacting to being assaulted and not the person starting the violence?

Do they just assume nothing bad will ever happen to them and thus can't empathize with someone being genuinely victimized? I can't see what they would gain from outlawing self defence. If anything, liberals are more likely to be assaulted since they tend to not workout and are more sensitive - see journos, they aren't even inclined to do petty crime and would benefit from people being sheepish about self defence. They would be the exact type of person a petty criminal WOULD target.
