Every stream mod is already empowered with feature/unfeature/delete buttons. Anyone who mods a stream has to decide for themselves what they want the stream to look like, what they find acceptable. I mod enough of them to know. So do you, it appears.
There is no such thing as true neutrality when it comes to content moderation. It's a comforting illusion, a fiction used to justify decisions and make them appear more acceptable.
Example:
imgflip.com/m/politicsTOO stream description sets forth exactly what the stream is: a place for liberal memes. You may not like the terms, but they are stated upfront. If you don't like them, then you can leave and go to politics or any number of other political side-streams.
Other example:
imgflip.com/m/Politics_Redux by contrast is content-neutral. There are stream terms but they do not relate to political viewpoint, only to refraining from harassment and abuse.
Third example:
imgflip.com/m/politics3 is even more free-wheeling. Not only are there no content rules, the stream actively encourages harassment in jest (spoofing off of "politics"). There's only one stream mod, and to my knowledge I don't think they have taken any mod action at all. I frequently use the stream to role-play a MAGA for satirical purposes.
I submit political memes to all of those streams, but I first consider the type of memes I choose to submit in order to comply with and build the character of the stream.
Choosing not to mod anything is a partisan choice, too. Based on the history of the internet, it's a choice that tends to attract those who are incapable of complying with the terms set elsewhere.
Free speech zones turn into hate speech zones, and the reasonable people who would otherwise frequent them flee for greener pastures where they can have civil and productive conversations.
