Flexible change another prepositon [closed]

Using "against" or "for" with argue shows you are arguing against or for a particular position you hold; you can't use it to mean you are having an argument with another person as in your example.

I am arguing with Tom. I am arguing against using the metric system, he is arguing for using the metric system.

If you said "I argue against you" it would imply your arguments were against the very idea of the other person - you could, for instance, say "I argue against you being elected to the board of trustees." It wouldn't mean you were actually having an argument with that person, though.
