You still don’t kill them, as long as first degree murder is a crime. Tim McVeigh had a “necessity defense”, too.
The mainstream pro-life groups condemned him and disavowed him. You’re a fringer.
The "so-called" mainstream groups had "spokespersons" who condemned him, because they feel they must be politically correct in order to appeal to what they perceive a larger segment of the general population thinks. That may, or may not, reflect what the members of that group subscribes to, but is somewhat necessary to keep the libs from labeling them as fringe, or radical.
I am anything but politically correct, and I don't give a Rat's a$$ what anyone thinks, but the Good Lord. Therefore, I enjoy the thought that the murdering abortion butcher is in hell, and there are innocent babies alive because he is dead.
