your point is clear and fair, however you didn't mention the other statistics
17 attempted murders, 41 bombings, 82 attempted bombings, and 168 arson cases
that really does change the relative weighting IMO ... but it's still a few orders of magnitude less than violent threats by large groups of people against other large groups of people. All the more so given their recent 9/11 track record.
Let all the abortion-bombers be prosecuted according to law as per normal, and let's also hope there are still those out there with some sense of perspective and true moral balance.
