As I said, I of course am jumping to conclusions and like all Transformers fans will wait for the movie to truly pass judgment. This was at best speculation and a vehicle to discuss the left's fascination with moral relativism.
The slogan in itself 'Our world, Their war' isn;t notably liberal, nor moraly relative.
The topic of the left's fascination with moral relativism is a good one and your observations are sound, but using 'Our world, Their war' as the jumping off point doesn't make much sense.
