To me, it depends on what the movement wants to achieve. If the goal is to offer knowledge to the individual, then I see no problem that there's fractions everywhere. A belief in FE would become a personal achievement of knowledge.
On the other hand, if the aim is to bust FET out as common knowledge to everybody, then it's bad news. In my opinion, this is what the various fractions must agree on first : What's the end game? A fractions community does not stand a chance being regarded as serious to the public.
A lot can be said about Eric Dubay. The guy is dedicated, but to me, and probably many others, he appears to have mental issues. Of all FET material out there, his 200 proofs that the earth is not a globe book is probably the worst, and IFERS as a whole is the most aggressive, hostile, closed-circle narrow minded community I've ever experienced.
