You have it backwards. I'm not chastising people for disagreeing with pro-lifers. I'm not pro-life. I'm saying that 40% of America hold a militant viewpoint in direct conflict with most of HN'ers. So when you say, "well, that's what happens when you offend 10% of the world's population", I'm saying you should bear in mind that much larger factions are much angrier about beliefs you hold.
I get your argument (Which is "What about that slippery slope!!!")
The issue with the argument is that normal people don't work in real, crazy absolutes. That's a certain type of technical person thing. Normal people don't get to Richard Stallman levels of consistency in action. They stop their environmentalism at perhaps picking up some trash or buying a Prius, maybe even bringing bags to the grocery store, they stop their pro-choice stance at perhaps sending a check to the tax deductible (aka, non-political) branch of Planned Parenthood
Google WILL eventually stop this sort of thing if it becomes pervasive. When it's isolated, and arguable that it shouldn't be fixed, they likely will not fix it.
It isn't like Google lets the billions of spam blogs effect search results when they can detect it's going on. They did at first, but once it became a problem distorting results, they stopped.
I get that you're trying to loudly assert "BUT THAT LINE HAS BEEN CROSSED", and the rest of us are pointing out that "that's debatable; Google surely will figure something out when it's and issue that's very clean cut".
Would you likely see action faster if were say, a conservative renaming of the liquid made after an abortion? Perhaps, due to those political leanings you ascribe to googlers. But will it stop for "left wing" terms eventually as well? Surely.
