[Avodah] two fictional sects

[David Riceman]

I'm idly planning out a novel about two fictional sects of Jews living 
in the Appalachians.  I'm curious if anyone can come up with evidence 
that either of these sects grossly misunderstand Hazal.

Sect number one argues as follows:

The Americas, because they intersect a westward line drawn from Israel, 
are considered iyei hayam and hence part of EY according to R. Yehudah, 
whose opinion they follow.  Furthermore, they argue that when the Mishna 
says about bamos "v'lo haysah lahem od hechsher", it means up to the 
time that that Mishna was composed.  But afterwards, when there was no 
unitary source of hora'ah, that din no longer applied, and so bamos are 
mutar in the Western hemisphere.  Furthermore, they argue that the issur 
of being makriv korban Pesah on a bamah applies only to a bamas yahid, 
and since theirs is the only valid bamah in the world, it is the bamas 
tzibbur.

It follows that they sacrifice korban Pesah every year.

Sect number two argues as follows:

The authority of the kehillah comes either top down, from a grant of 
authority from the king, or bottom up, from a grant of authority from 
its inhabitants.  The authority of previous generations to bind later 
generations is mediated by the kehillah: if someone moves to a town with 
a different custom he is not bound by his old town's customs, and, a 
fortiori, if he establishes a new town he is not bound unless he agrees 
to be bound.

They establish a new town where only dinim d'orayysa apply, arguing that 
the whole authority of derabbanans disappear without consent.  
Furthermore, since they don't consent to be bound by a local kehillah, 
and certainly the US government does not grant them any authority, they 
argue that all the dinim associated with "b'nei ha'ir kofin ..." do not 
apply to them, even though they are arguably d'orayysa.  They 
acknowledge that Jews have an obligation to have a court enforcing 
criminal law, but argue that that obligation is fulfilled by the secular 
court system.

So we have a highly organized and hierarchical sect meeting a wildly 
anarchistic sect, both claiming to be authentic representations of 
Judaism, and each acknowledging that the other also has a plausible case 
to be made for it.  And then there's a mysterious murder ...

I know it's implausible, but are there blatant halachic holes?
