Interesting discussion of relationship of galaxy rotations to the state of the early Universe.

It most certainly is. Half the Universe sees each galaxy as clockwise, and the other half sees it anticlockwise! [On average]
However, as the link describes, it is possible for large scale imbalances to arise if there were regions of the early Universe with significant angular momentum.

I am not sure what you mean by "accepted norm". There are empirical facts, which are the subject of research. The Great Attractor and the Great Void are large scale density variations.
Inflation should probably lead to a lack of large-scale correlations in angular momentum early on (by dilution), so after this it could probably only arise by some sort of large scale gravitational interaction.
[COMMENT DELETED]
Momentum is conserved, and so is angular momentum, which means that in order for something to rotate, something else has to rotate equally as much, but in the opposite direction. BTW RPaulB, the universe is flat with a 0.4% margin of error, as I said in the 'what is the shape of the universe' topic. You might want to read that.
