Going into off topic territory, but...
No particular thread, he's just around on the Wii board. Dude is called SF_Baha/DarkZero920. He just trolls all day and says the dumbest shit possible. It's also funny because he calls Xenoblade a mediocre game without actually owning it. And he was also making a huge deal about people modding their Wiis to import and how that was illegal, etc. This sprung out his insane region free comment.
The sad part is that he's serious. Talking sense into a troll doesn't work, unfortunately.
Take your pick of threads, especially in later pages:
