I mention facing liturgical east only insofar as w are all facing and worshipping together in one direction.  If each man wanted to face his own way (up, down, all around) would really be worshipping together?  We certainly wouldn't look like were worshipping together anyway.  St. Paul said we are to give God "right worship".  It seems to me this means, when we pray together at the sacrifice of holy mass, we do indeed "Pray Together" in fact.
As far as your supposed litany of the horribles viz. Christianity: I'm not sure where you're going with this, but if it sucks so bad, by all means feel free to try something else.
