Derogatory remarks never help(s) either yourself or others.
It spoils the environment and if there is any semblance of empathy between the parties, these remarks kill it.
Instead, look at it emphatically, look at it from a down-to-earth view, look at it from the eye of a child.
Try it for a couple of conflicts and see that conflicts vanish away, in-fact the other person is happier to resolve any differences.
