You don't need macros in Red (but it's easy to roll out your own macro layer, if one so desires [1]), all code transformations can be achieved at runtime. A brief explanation of how this works is given in [2]. As for Red / Rebol vs. Racket content - I wrote an excessive post on that some time ago [3], in response to similar question. TL;DR from language creation perspective is that Racket has state-of-the-art macro system and all the necessary infrastructure, and Red has metaDSL (that is, DSL for creating DSLs) called Parse [4], which is basically PEG on steroids (think OMeta) + a different take on homoiconicity, compared to Lisps, which, most of the time, renders custom readers and tokenizers unnecessary.
