MN is not Reddit and that should be celebrated.
The fact that I or other TWs can post here at all without being instantly evicted is the difference between MN and reddit/GC, regardless of whether or not I am pulled to bits or drowned in honey.
As biased and one sided as it is, MN/FWR supports actual debate, and employs professional mods. Reddit OTOH is a collection of self-policing echo chambers. If you disagree or oppose, you are toast.
If you want to understand r/GC's fate, look into the story of r/The-Donald which has been more widely reported on and for longer. Essentially both communities distilled themselves into a hive-mind of toxicity.
