I don’t think you understand this. Either that, or I have received bad information, and would like to be corrected.

They’re not censoring pro-Palestinian messages by their users, or in fanfics– I would not be supporting them if they were!

They are– to the best of my knowledge– requiring that a staff member/moderator not use their official AO3 moderator outreach to spread political (in this case pro-palestine) messages.

ETA: I have decided that this is too much of a hot button issue to be worth commenting on and fighting about right now. Post closed.
