Back on Reddit there were people who set up scripts to automatically delete comments after a set amount of time to prevent people from looking at their history. As you could probably guess, they were usually the most stubborn and argumentative sort on the platform.
Though I’ve upvoted that user before and I normally don’t do that to people being disruptive, so who knows? If only there were some sort of history that would tell me what kind of user they were…
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.
