No, I didn't dismiss it. The meme is about the battle for tenochtitlan, not about everything the Spanish did in Latin America.
Latin America? Tell me, tell me when the Roman Empire arrived in America? The great feat of the discovery of a new world (literally) was that of the Spanish Empire, that's why Spanish is spoken in America and they pray to a Christian God (among many other things). It is called Hispanic America, and they are Hispanic speakers.
