When do people hate on Sasuke? I have seen that when the fans incite something and overrate Sasuke, so then others might just bring Sasuke down a little to balance it out. :shrug: Also if Sasuke was like Gaara, then I don't think that he would have too many haters.
People shouldn't be called a hater just because they have a different opinion on Sasuke. Just because someone thinks he is arrogant, doesn't mean they hate him. Just because someone thinks Sasuke gained power from others does not mean they hate him. etc. I have seen those situations and they get called haters even though they are just giving their opinion. I wonder if people just like it call others haters. Naruto gets criticized many times and yet people look past it. So it's hating to say Sasuke is weak, but not hating to say Naruto is weak? They both have gotten criticism.
There have been threads bashing Naruto, yet barely anyone will say that they are hating. But when a thread is made about Sasuke, people might post "haters gonna hate" memes or whatever. Sasuke just gets put on the spot more because he has more fanboys, thus the fans might get offended by any comments that imply Sasuke can't do everything.
People should be allowed to post opinions/views without being called a hater because they think Sasuke will lose against Naruto whom has Bjuu mode. And also: so it's alright for people to say Naruto's power is not his, but it's not alright to say that Sasuke's power is not his? They are both in the same situation. And a few more reasons: maybe it's his fans, that he is arrogant about his power, betrays others, he wants to do the same to others that was done to him (hypocritical).
Seriously though, he is an anime character and I doubt a lot of people actually hate him. I could be wrong though, but just stating what I've noticed. A lot of characters have been criticized. Also though, some people might just not like the villains and well Sauke has been a villain. Ok I'm done, but just trying to put it into perspective, because I don't know how many of the "why do you hate Sasuke?" threads have been made, although I've seen a few already.
