“Anti-life groups� refers to what groups?

I know of no such groups who are anti-life

NARAL, specifically. They referred to Roberts as an "anti-choice activist." Planned Parenthood also refers to "anti-choice zealots." These two groups specifically would fall into the anti-life group. They tend to prefer the death of unborn children to any other options.

I know of no such groups who are anti-life, except perhaps weapons manufacturers, "war presidents", and those administrations that concoct reasons to go to war and then redefine the word "torture" to legally permit themselves to torture those they didn't get to kill.
