I don't take offense to the words that were used. It's more akin to articles that use absurd fonts or blatantly poor color schemes. Such things are unnecessary, and make it more awkward to absorb the actual content.
When I see authors doing things that obviously make their work harder to read, it does make me question their judgment, which in turn makes me question the validity of what is being expressed.
I pretty much agree with you, though it certainly depends on the context (I'm more likely to not be bothered by it in a post on a mailing list). But for a technical writeup? You want to be treated like a professional, write like one.
To be clear, I am not criticizing you for finding certain words to be offensive or thinking that they are offensive words. I am criticizing you for questioning the validity of the article because the author used certain words that you find/think are offensive.
