Normally I would say people can use whatever GIFs they want to use. (I rarely use white women in my GIF expressions unless there’s no other option, primarily because I’m attempting to have a mirror image of me. But there are three popular ones I use a lot: 1) that little white girl who is chewing with her mouth open and saying “I Love It” 2) another girl who looks sorta Latina and scrunches up her face like her heart is full 3) this little white baby getting low and dancing her ass off.
But going back to the topic at hand, I do see your point especially if you don’t understand the context of the GIF. A prime example is this tweet of Diddy dancing in a clown suit. His tweet says “Trump leaving the Oval Office after losing his twitter battle with John Legend and Chrissy Teigen” with the hashtag Chrissy started.
But the GIF totally missed the point. Diddy was extremely scared of clowns, and there was a whole backstory about it on Ellen. He was overcoming a fear by dancing in this clown costume, along with his sons. So that particular GIF to describe Trump made it seem like he was heroic and overcoming the odds instead of the “clown” insult it was supposed to be.
This is exactly why I skip GIFs when I don’t understand the reference or it’s not immediately obvious.
