Folded to Blinds - Late in $11 Rebuy

[Macdaddy Warsaw]

Unfortunately I got moved right after this hand so I can't provide a hand history, but I remember the hand pretty well. Not interesting after preflop anyway, but here goes.

It's folded to me in the SB with about 40k stack with 600/1200 blinds and Antes at 75. The BB has about 14k. I have A9o. I make a standard raise to 3600, he pushes, and I call. My standard operating procedure.

I live with SmileyEH who happened to be walking past during the hand. After I made the raise, he said, "Just push, you can't fold to a raise, that's a huge leak not pushing there." I disagreed and gave him my reasons which I'll state here later, but he holds onto his position and I'll give his reasons later too as well as results although they're not important. Also, no read on this guy since i just got moved to the table less than an orbit ago.

What do you guys think?
