So you're claiming ignorance in defense of racism. Convenient how you stood up for him, didn't bother checking the blatantly obvious post of why he might have been tagged as Yusuke, and immediately had things turned around.
When you left the "Fuck You, I was right" comment, I had already explained why you were wrong later in the thread. The fact you still think you were right, and are swearing in my face when I present you with it again shows loads for your character.
Fuck you, you defended a bigot, and now you're claiming ignorance.
