I would guess it might fall under personal attacks.
I've read all of his books, but I'll admit in my opinion, some have dreadfully difficult to get through.
I agree with your statement. And yes, so far he is the only author that has disappointed me so much I think twice before buying his work. He has made several statements to me that I thought were over the top. Sometimes, I don't post just because I don't want my opinion torn to shreds.
I know THAT feeling. Like I said, lack of consideration towards others in a fiction author--whose job it is to understand motivations and the effects of words upon different types of characters (not just clones of oneself)--is something I find particularly irritating. Either it's deliberate (and given the job description I just cited it could be), or it's a case of being oblivious of a) how one sounds or b) how others actually regard said behavior.
If someone is deliberately being rude, then they sure won't get my money...why should I reward bad behavior?
But let's say it's the second scenario--just being oblivious. When I see that sort of behavior, I find myself less able to believe that author's characterization or forgive the flaws in that area. After all, if there is a lack of understanding of real-life interactions, how can I expect to read a book with convincing and diverse characters whose motivations and emotions make sense? If the author has little experience in connecting with people who are not very, very similar to him/herself, then what is there to inform the writing? Merely studying interactions in the academic sense will only carry so far. And if you get in the position of having to write about emotional experiences you've never had (and dealing with as many aliens as Trekdom does, that's par for the course whether you're single, married, or of any belief persuasion, etc.) and get your audience to buy it, it takes a tremendous degree of empathy to get people to buy it. If that's lacking, it's going to fall flat.
It's no coincidence, perhaps, that this is the exact failing I found in Torrent Sea--what character action we did see was in a wholly unsympathetic vein...that is, when the characters weren't doing a Michael Crichton and taking a complete backseat to the various scientific ramblings. Once I knew that lack of interpersonal skills was there, I couldn't un-know it and the results in the actual product were blatantly obvious. Now, I will say that Torrent Sea was probably the weakest of his works thus far and other works didn't exhibit the problems to quite the same degree--so that was also a factor. But, based on Torrent Sea AND the unfortunate behavior I've witnessed here, I can safely say that should I read his books again, I'll be making a trip to the library. Or going to the "library" that only has new books and a coffee shop in which to read them.
