Personally I think it’s more of a fuckup and PR misstep rather than endorsing any particular world-view.
Nah,
If they admitted they hadn't done their research, apologised for the matter and promised to be more careful in the future, it would have blown over in a day and their community would have retained their respect for them and it would have been looked back as a brief fuckup / pr misstep.
Instead they went into detail about how one of the two controversial parties has changed and said nothing about the other party, except to say they wanted a big tent (which is a massive "dogwhistle" for we allow the intolerant into our space and will let them be intolerant to the detriment of all others).
When asked for clarification and given the chance to explain what they really wanted, they went silent and haven't responded since.
That silence speaks volumes.
