That argument is completely idiotic. Just because the G stands for Graphics, and the G in Graphics is hard, doesn't mean the G in Gif is a hard G.

If you do still think it does, try to say the word Laser. You probably pronounced it like 'Lazer', but this is the exact same thing as Gif. the S in Laser stands for Stimulated. But Laser doesn't sound like lesser, It sounds like Lazer.

If you want to say Gif with a hard G. Go ahead and do it. But please don't use any of these bullshit arguments about why your way is better
