Stop trying to define what a "real fan" is. I actually like the new forme, but it's absolutely ridiculous to dismiss someone else's fandom just because they dislike one of the classic Pokemon getting a new form with a very polarizing new look.
A real fan also isn't a delusional personal who just follows every beck and call of whatever they are into. I personally don't care either way about Newtwo, not like I'd use it anyway. There are things about it that are kind of cool and things about it that are kind of stupid looking.
