Because you asked for it? Someone posted a dumb meme and didn’t cite it with studies and now you are mad. You do have some burden since you are the one who started the discussion on proof in the first place. If you can’t even be bothered to look at the proof they bring, its not their problem.
There is no secret agenda here. Its just a dumb meme. You can a meme with the words “shifting baseline syndrome” if you want. In fact you can put whatever you want in a meme.
