I mean...that should not surprise anyone with a modicum of honesty and/or a conscience. This is what these people do: they take, at least what they view as, the most outrageous element of some service provider and morph it into an entirety with their little chickenshit emotional appeal gimmick. Planned Parenthood's abortion services accounts for somewhere between 3-12% of what they do, which means at least 88% of what they do is exactly not that. Third trimester abortions constitute less than 1% of total abortions, and virtually all of those are triggered by some sort of medical complication that arose late while the rest have to do with restricted access...
...but the same people you're describing would have us (and themselves) believe that all Planned Parenthood does is perform partial birth abortions on women who just suddenly changed their mind about the whole having-a-child thing because they suddenly realized it interfered with some trip to Cabo. They're easily the most dishonest people you'll encounter in terms of political discourse, so it shouldn't surprise you at all that douchebags like Paxton are doing this type of horseshit either. This is just more of the same: the so-called "party of small/limited government" taking a huge interest in what other people do with their peepee parts.
