Re: Why did they bother...
Remember: Post, not poster.)
What you say here, of course, is perfectly reasonable. Ad Hominem
attacks are, generally, bad form in argument. You have successfully identified and warned about the use of an informal fallacy.
No, we don't have to call this "ad hominem,"
but this is the appropriate label. Sure would be odd for someone to outlaw using this term. It would almost seem like an attack on reason itself to outlaw reference to words which point out common errors in reasoning, wouldn't it?
You're lecturing again.
