He's been a pretty good roommate otherwise, usually cleans up after himself including others, does the dishes, etc. However, lately he has become nearly intolerable with his attitude, and it seems to only get worse.

Everything is a debate with him and he won't stop until he believes he's won or has decided to walk away with a snide remark as he leaves. I have broken these moments up multiple times, stating "this is such a petty argument, why is this being made out to more than it is?" only to be answered with a tirade of why I'm wrong to make such a statement.

Whats bothering me the most is, while I would typically listen to his rants about work and such with open ears, I'm not granted the same luxury. I can't state an opinion of something that's affected me without being ultimately lambasted for it. At first, I assumed it was him playing devil's advocate (which may still be the case), but I'm beginning to believe he just doesn't want to agree on anything.

I've seen this before with roommates (not mine necessarily), and it's nearly always been coupled with disdain for the person they argue with. 

Does this seem likely or does my anecdote only reach so far?

I know I'm getting thoroughly fed up with the door slamming every time he appears offended that I won't argue with him on something (for some reason, just saying he was right last time prompted a serious door slam and speed off in the car).

For the record, I've moved beyond being a passive-aggressive roommate long ago, but he's younger than all my previous roommates by a fair amount and am worried being blunt is going to cause more problems. 

Additionally, I'm not moving because of him.

How would I best handle this situation?
