Well, what the man did is criminal. Whatever his motivations,
  they're criminal. They go against the laws he is bound by in
  being a citizen. His reasons don't matter so much to me. Even
  for those who may cheer at his actions, THEY didn't go out and
  commit violence. They're just going "yay guy woo". Empty words.
  It's the act of a man who deserves punishment by civil
  authorities. It's an uncommon act. In fact, it is VERY uncommon.
  Even among the percentage of people who are pro-life by
  ideology, consider bombing clinics the work of an extremist, a
  terrorist, a murder - pick your favorite word. Then within the
  pro-life there is a small subset who says, "You're doing what
  I'd never do and good for you" Within that small subset is
  another micro-subset and that's those that really WOULD do what
  he did. Then within that small subset of the micro-subset are
  those who WILL do it.
