Difference between "gger" and "gga"? [I Race Cars]

I know, spicy question. I'm not gonna treat y'all like idiots and say "duh same defuhnitionzzzzzzz?" Come now, I know some are fine with "gga" and some aren't, I know most if not all are NOT fine with "gger" give or take extreme nationalists. ANYWAY!! I don't mean to step on anyone's toes but I personally have always seen them as completely different words whether used by a black person or white person or even a purple person. gga is and always will be "boi, bro, brah, dawg, homie, friend" in my eyes, and "gger" is just blatantly racist (unless used in educational sense obviously) HOWEVER!! I wouldn't just run around the streets saying "HEY NIBBAAAAAAA!! HOW YOU DOING NIBBAAAAAA?!?! I'M FINE NIBBA!!!" Having said that, some seem to think "gga" is as bad as "gger" if someone whom isn't black says it. Of course, it really depends on the relationship between whom says it to who, BUT IIIIIIIII have always seen it as a non issue since they're both so distinct in their meaningsssssssssssssssss!! Still, I am courteous enough to not say it when I shouldn't and I ain't throwing aside anyone else's opinion just because IIIIIIIIIIII don't think it's so bad. ┬┴┬┴┤•ᴥ •ʔ/

Excuse the rambling, had a bit to drink tonight and I'm feeling more confident than ever to post my thoughts.
