Do you back down from arguments or are you a "raging bull"?

Whenever or indeed if ever this situation arises, how do you react? Maybe you avoid confrontation at all costs. Or perhaps you stand your ground giving as good as you get. Yes, it depends on the criteria involved in any dispute or disagreement, but in general what would you say your methods are? This can be with anyone at all, friends, family, work colleagues, chance encounters.
