my argument is more philosophical than scientific, so I can offer no evidence

time is asymmetric BY definition. if time weren't asymmetric I would have to call it space instead. (seems like I'm using asymmetry and monotonicity as synonyms)

in my definition, passing is all time can ever do, and it must do it only in the 'same direction'.

finally, in my view it is space which enables backwards and forwards motion.

I don't follow you here. If time were not asymmetric it wouldn't suddenly just be space. What are you actually claiming here?
