I dont care what anybody says, G is not a vowel and should never say it's name.
However, if G can also make a J sound, and J never says it's name either... why do we even have J?
Also the dude who brought this up (a Youtube commenter on a south park video) is still responding calling everybody who says gibbing with a g handicaps and "stupid parrots". He makes lets-plays by recording his screen btw.
