He has multiple girls into him despite being awkward at time, he has high Cha.
Yeah, he was a condescending sexist prick to the Kiyoshi warriors (initially), and while it did earn him some beatings, it didn't get him a restraining order and he even got with Suki in the end. That's high CHA alright.
I don't know about you, but to me, the fact that he showed genuine humility and willingness to step beyond his initial chauvinism (after some hands-on lessons about fighting women) had a lot more to do with that than his charm.
Right? His main squeeze met him by kicking his ass over sexist comments. Classic Bard shit.
Meet enough people and there will be at least one who is into jerks.
Depending on the person, being awkward can be charming and sweet.
His CHA was high enough that he kept rolling low and saying silly things and it still was good enough.
On the contrary, if you keep trying then eventually you'll roll a 20 no matter how low your CHA is. That's good enough in circumstances where you do get to keep trying and you only need to succeed once. Sokka would keep trying while Zuko would refuse to risk looking like a fool.
That's rough buddy.
We all praise Sokka, but let's not forget that the live action actress of the princess got a dick haircut, the ultimate bard haircut.
