Because everyone is human, and we all have an intrinsic value.
If you forget that, you'll be quick to dehumanize groups that you view as "opposing" or "other" and you're stuck in the same tribal game that keeps this hamster wheel running
I'm sorry but that goes against the settled Sciencetm on politics. Progressives are always right and all their demands are good. And if someone is too uneducated or isn't in the right social circles to be able to understand the latest Sciencetm on things such as gender, they're a Nazi chud we need to exterminate.
I mean the progressives are obviously right... But quarreling doesn't help until we can break out of this system. There are things that must be fought right now, but we need to pick our battles and focus on the bigger problem...
