In the early days it was an abortion-adjacent topic, which made it an easy target to vilify to rile up support from single-issue voters. Now a large portion of society will hate anything involving stem cells forever, regardless of facts. Once the culture war starts, it’s hard to get it to stop.

That one still ranks as the all time top WTF sale.
