Actually, I made that remark because I simply noticed that on this round we had mostly opposite votes, 12 opposites out of 26, if I've counted correctly. I'm also aware we don't always agree, but in previous rounds the difference didn't stand out too much for me to notice. So I simply thought, "oh, this is one round where we are largely on the opposite sides of the fence".
It's true that I don't really like Haruhi very much. I can see that she's a "must vote" character for you in much the same way Kanade is a "must vote" for me, but trust me in that I'm voting against her simply because I don't like her very much. (I'm not saying you implied that I vote against her for other reasons, but I'd just like to tell you my reason. )
Best of luck to our Sayaka in today's AST match! She's currently leading now by 63 votes, I'll share with you the (unofficial, may contain some fake votes) vote tracker link as reference for her progress: http://fc.jpn.org/ast2011/
I look forward to the day we get to support her side by side in ISML next year.
