Eh, hating FF13 isn't too cool anymore, since FF14 came out and was even more shitty, but even the hate for that has moved along, though I personally hate Square and everything they do, I have never made a hate thread about it, or anything in particular, and probably never will. Really the hate has died down, though it springs back up whenever news of a new FF shows up.
Twilight is always hated, and unlike the other options, there really aren't any fans around to defend it, and with no fans bother, hate threads don't really stick around.
I have honestly not seen a single MLP hate thread, then again I haven't been looking. I do think they're kinda silly, I personally hate the connection to 4chan it has and I'm looking forward to this particular trend passing, but honestly, I have yet to see any hate for it.
Bayformers? Been too long since the last movie came out, people don't entirely care right now. They probably will when the new one comes out, though.
Ah yes, Sony. Honestly, this is probably the most popular thing to hate right now, on your list atleast, but there are still more sony supporters than there are sony haters, by my count. again, this trend will pass, and people will go back to hating other things.
Honestly, I'd say Halo, CoD and FPS in general are a usual safe bet around here for "things the escapist community hates on". I'd also say BioWare is getting quite a bit of hate lately, partially left over from Dragon Age 2, and more yet from people jumping to conclusions about some of the recent news about Mass Effect 3. Hard to tell if it's around the same level of Sony hate at the moment, but I've begun trying to make a habit of just avoiding anything that might be a hate thread around here. Makes the site a lot more pleasant to be on.
