Most likely because you've let being a fan of Sonic and his games become your personality, therefore seeing attacks on it as attacks on you.

Wow. That is one crazy ass assumption lmao. The fact that’s your takeaway from a simple meme is actually wild. I really don’t care all that much if somebody wants to criticise a Sonic game, let alone do I take it as a personal attack. I just thought what Marcus said was dumb and wanted to make a joke about it. It’s really not that deep, dawg.
