Can we quit the "B...bbb.bbbbut he's an ABORTION DOCTOR comments?" They've already been done, and are only applicable to the point of this thread in that his particular line of work would be considered by some to be "high risk."
Good point.
This thread is to discuss a practical issue, not an ethical one.
Jumping into pro-choice/pro-life discussion wont bring anything but unneeded arguing. While talking of what a person in such or similar circumstances can do to protect himself is beneficial.
Finally, abortion docs aren't the only ones who can be targeted. Think of lab animal researchers or fur manufacturers.
