I was referring to the text at the bottom of the press release:

By signing the petition you take a stand against a false narrative that downplays Africa’s vast size and diversity as the second-largest continent, reducing its perceived importance in global politics and economics. You can correct the narrative.

It seems to single out Africa because this campaign is led by Africa No Filter and Speak Up Africa. I just thought it was amusing that the campaign text mentions Africa repeatedly but only indirectly mentions south america when referring to the global south.
