I actually do agree with him on some things when he has the asshat turned down to 2 or so.
I think where Sydney is going is the point that seemed to come across (not saying this is what you said, but this is kinda how it came across) that "if he didn't get hazed, and more importantly if he didn't get hazed in the way I'm accustomed to, he isn't a brother of mine." It's like the old "pledging vs paper" debate that the NPHC groups have.
I know that the sisters that are joining my group now have a pledge process that's VASTLY different from mine. I'm sure mine was vastly different from some of the women who pledged the same time as me at different schools. What matters to me is how I get along with them, and more importantly, what they give. Just because I can't require you to learn history doesn't mean you can't go ahead and do it anyway. If you do the least amount of anything possible, it doesn't matter how or when or where you joined, the respect you receive from me will be nil. That doesn't mean hazing. That means you do things like showing up at the house just to hang out (not only when you have to come there for meetings), helping with rush nametags when you didn't sign your name on a sheet to do it, etc etc. That goes on throughout your whole Greek career, not just pledgeship.
