Bob is living proof that he's right, at least on a case by case basis.
Not to mention he's an idiot whose understanding of "intelligence" is arrested at the age of Calvin and Hobbes; as far as reality is concerned, such as if one uses evolutionary psychology as a reference; "intelligence" in a vacuum is just one of many potential "tools" (just as there are many different forms of "intelligence" to begin with, none of which Bob could even elaborate on in any margin of depth no matter which IQ test and testing standards he was referencing).
If, in practice, intelligence doesn't serve any useful means or ends, then it's not to one's benefit at all, and if anything, fetishistic it "in a vacuum" would arguably be evolutionary recessive.
(I honestly don't think Bob's particularly intelligent to begin with, or reads much of anything beyond the 6th grade level, but even giving him the benefit of the doubt, it's obvious that his intelligence hasn't been effective in allowing him to do basic, evolutionary desirable functions such as consentually mate or reproduce, so in reality, evolution could care less about "intelligence" unless it serves the right means and ends; if someone supposedly with "lower" intelligence (or heck, even an chimpanzee) is able to reproduce, then it's more evolutionary effective and desirable as far as biology goes, anyway.
Bob, in comparison is just some evolutionary ineffectual refuse, who is continuing to flex his mythical "intelligence" in a redundant and defective way, showing no ability to adapt or put what little intelligence he has to any effective use to begin with. (For that matter, the primary end as far as "evolution" goes is an aesthetic one, as is documented in "Survival of the Beautiful" and other books on the subject, which I'm sure are above Bob's reading comprehension level.
intelligence or any other traits is only "worth" anything if it provides a means to an aesthetic or creative end (e.x. intelligence used to create something aesthetic and well-designed, such as a Ferrari, is evolutionary effective intelligence; intelligence which serves ineffective and aesthetically repellent ends, such as 99% of Bob's trashy and cliches posts, is worthless in and of itself.
