If someone can't state their point without warping the very language they use to support their point, it makes it very hard to feel like anything they're saying is credible. Example 1: someone is trying to convince me to vote Republican. They go through the Republican platform issue by issue, and compare/contrast it to the Democrats' stand. However, every time they use the word "Democrat" they instead say "Democrap"…
He refuses to use the commonly established language which distorts reality. It is a radical choice (given how well established the manipulative language is). I can see how some may find this irritating. You may want to take a look at this lecture to see why language is so important and influential. http://m.youtube.com/watch?v=5f9R9MtkpqM
