Argument and verbal conflict are two different forms of dscourse. The former is a logical approach to settling different viewpoints on a subject, while the latter is most often unproductive and can lead to violence and loss of friendship. The best way to settle the latter is simply to agree and refuse to pursue it further. There are, of course, people who begin arguments for the sole purpose of creating a situation in which they attempt to visit violence or other unfortunate behavior upon the other person. Those people will often not be dissuaded, so it isbest simply not to have anything to do with such individuals.

Walk away. I don't like argue

Easy. Ask them to validate anything that doesnt make sense. In my experience people whom like to argue never have scienitific backing for their claim or theory. So when its clarified as a claim, statement, or theory, there lies no reason to argue.

I usually give my palm for them to talk with. LOL
