I don't get notifications when somebody quotes me, so if you have questions, it's best to shoot me a pm. But since I happened to notice this, here's my verdict:
Yes, we do expect the text to be read as it was written, so no omissions because you're uncomfortable with a racial slur or find something uninteresting. However, we do allow readers (and in particular soloists) to choose whether to include things like footnotes, and we don't expect figures to be explained or figure captions to be read. We often treat pages and pages of tables that are just numbers as figures and leave them out.
However, in this particular case, the tables are very short and benign, and since it's only those 5 in the whole text, I would ask you to include them. This chapter has a lot of numbers already, it seems that he tries to summarise them again in the tables to make his point.
Also, just for completeness: "The listener can just download the text and read along with it" is not a good argument in general.
First, they would need to have access to the internet while listening and be so inclined to look at the text - many of our listeners do so while doing housework or are on a run, so that's not easily possible. Second they would have to stop the recording to read the stuff in the gaps, which I personally find annoying. And finally, you never know where this recording will be downloaded from - our catalog is distributed widely, and many of these places do not include the text link, sadly.
Hope this helps.
