But yeah, fans are just really passionate. Really, really passionate. After all, the narrative is that it's all their fault the series has fallen apart - I don't agree with it, but it's too late to change it now. They're bound to take everything personally, and when things get personal, people stop filtering themselves. Combine that with the shushing and put-downs from other fandoms, and it's basically them VS the world. The 4 years of poor, poor decisions from Capcom in general have not done much to redeem the company, either.
It's an entirely different set of producer/consumer and fan-to-fan relationships than what most gamers are used to, and some posters react to everything MM-related in a metacontextual way. All the time. Every time. No matter what. It's just the state of the fandom at this point.
