To give a specific example, I was part of an LGBTQ in Tech Slack group that was admined by several members of the community mentioned above.

Their CoC indicated that anyone considered a majority group (white and male being the worst) would automatically be considered at fault in any/all arguments and they would be resolved in favor of the minority.

That's the mentality at play here that does not give a space for people to defend themselves and resolve conflict. Sweep it under the rug so as to not disturb the more sensitive fringe elements, and condemn those who have not had a chance to even consider repenting.
