You insult me, and then say that we should stop an argument? Great idea, bro. Thats the perfect way to end such a thing.
And then you go on using my words against me, making yourself look like a fool.
Storywise, the LS is around, storywise, Sora didnt fight the LS. Sora was in the Dark Realm after the Xemnas fight, then he got the letter and went back to destiny islands. There was no inbetween fight. The next we hear of Sora is BBSs secret ending, and that is it.
And as far as Ive seen, Nomura said the dialogue wasnt canon. We are at a standstill, which you should have seen miles away.
And what do you mean, according to who? Riku isnt a master, Terra isnt a master. Listen, as far as we know, there are only 4 specific masters in game: Aqua, Eraqus, MX, and Yen Sid. Anyone saying any other people are, is most likely wrong. There were more masters in history, but we dont know their names, who they are, etc.
If you really wish to end such an argument, as you say you do, then thats fine. Im fine with ending it, now. I didnt add any insults, in any way, in here. Ill play the role of the more mature person in this situation, now if you want to end it, end it maturely.
