Why?

Can anybody tell me why I would continue a dialogue with someone who doesn't want to hear what you have to say, puts words in your mouth, tells me what I think, who thinks they know what my position is, catagorizes me and employs straw man and red herring arguments to keep the conversation going in circles? In my line of work, I've worked on the opposite side of lawyers who do some or all of the above. Most of them are crotchety old nags working in solo practices who find themselves knee deep in needless law and motion proceedings and on the business end of a judges order for sanctions for one reason or another. In the end, you have to feel sorry for them. A little humility, grace and intellectual honesty would do them well. But who am I to say and what do I know...I'm just a squirrel trying to get a nut.
