I didnt call anyone dumb. If youre taking it personally that people think pronouncing GIF, an acronym that stands for Graphical (with a hard G) image format, "jif"is dumb, then maybe you should examine why the pronunciation of that word is such an integral part of your identity. But if you're so proud of the trivial knowledge that you read in a sentence on a website that you feel the need to lord it over others and consider it a personal affront when people think its silly, then yes maybe you are dumb.
