Yeah, you have a piece of code named "the kernel" which you can point at and tell that it isn't bloated. But you can do this in Linux too, if you compile everything as loadable modules. That is just creative accounting of the bloat.
It's only marketing spin if you will always need all of the features in order to do anything meaningful.
Are you still having this debate with a purely academic definition of "monolithic" vs. "micro" kernels? Because neither of them exist anymore, and haven't for a long time; it's like CISC vs. RISC, in that arguing about it today is really missing the point since most everything is a mix. You need to address what Linux actually is, and what real microkernels exist, and what real performance they have, not regurgitate boring arguments from the 1980s that have simply been superceded (rather than one side "winning").
In fact, this goes for all you other commenters still having this argument. "Compare and contrast a microkernel running on CISC vs. a monolithic kernel running on RISC. Which will run best on a top-of-the-line Amiga, and how can this be best leveraged into flaming those who disagree with you?"
