Actually, it isn't. The opinion that that "everything Takara does is by default better than Hasbro" is indeed still alive and kicking. I, for one, am of that exact opinion. But as soon as you use the word "fallacy", your statement loses its validity, as opinions, by definition, can't be false.
Regardless, you're probably better off just stating your own opinion, as opposed to critiquing anyone else's.
