The writer should be more careful- it's not a button that mutes Whites, but rather a 'sticker' that can be posted in whatever passes for chat on that thot-image dissemination system.

I don't use instagram, but Whatsapp pulls its gifs from the same place and for weeks the ones that pop up first are "vapid BLM slogan over childish doodle of a wog", when they aren't anus-related rainbows. Search will bring up many more, but if you put in right-wing stuff you'll either get no results or negative ones.
