I agree with him in disagreeing with the conventional wisdom of 115 being a more talented division. I also agree that it could be caused by a bias in favor of strikers over grapplers, because I feel like I have encountered a bias toward the better strikers at strawweight several times now. Some guy is ranting about Joanna's beautiful striking vs Ronda's amateur grappling just now in another thread actually.
There may be plenty of other reasons people think 115 is better. Perhaps the division is newer and not dominated by one fighter and thus seems like it has more potential.
But for all your talk about BigMuffler not having an argument, he has made an argument, though you disagree with it. Your argument in two comments to me thus far is:
1. that I ought to know better and
2. that he is a dummy.
If you are trying to persuade me, then give me something to work with.
