I believe the only method to moderate regarding hate speech is complete deplatforming. Anything less is tacit agreement through inaction, and tacit agreement leads to the misguided opinion that overt racism, homophobia, transphobia, etc are acceptable in a public forum. It is ultimately the MD administration who can decide what is and is not acceptable for others to host on their servers, and if they decide it's okay to play host to inflammatory content and hate speech, the exclusionary and predatory nature of bigotry dictates that eventually those elements will be the only elements that remain, as anyone I would consider a reasonable user would not want to participate in such a group.
Similarly, expecting every user who is opposed to open racism to block the many racists emboldened by their freedom to share their hateful opinions is unreasonable.
Fortunately, they have decided to take action against that garbage hate speech. Unfortunately, they do so in a very "both sides" way, quietly equating the good and the bad as "political content". That's what is disappointing to me.
