Siding with a website or not, that is his choice. Why try and impede so many inconsequential things as a "fan" when he can make his own decisions without you trying to impose what you believe onto him?
More telling that you are an alt account, your credibility means nothing due to post history if your mannerisms, your obsession with continually bringing up drama, and now a tell sign of you even behaving the same way as the crazed fan and parroting their beliefs. And now you trying to tell Mofu how to act? I hope he does what he chooses to do
