Are you asking for spoilers (i.e. will there be any more cross-dressing jokes)? Or are you looking to drum up a discussion on the topic?
Regarding the former:
I can only speak up to the latest weekly release, but I see little evidence that cross-dressing jokes will be a major part of Bookworm. It hasn't come up again so far. If it does come up again, I would be surprised if it were more than a paragraph or two.
Regarding the latter:
It's OK if this bothers you. You don't have to read something that you find upsetting. It may be that you will simply not enjoy Bookworm.
But I really struggle to sympathize with the idea that a mere political misalignment with the author can completely ruin an entire series. This strikes me as a prudishness more than progressiveness. I'm reminded of my born-again-Christian friend who stopped listening to Smashing Pumpkins because one of their songs contains the lyrics "God is empty". In my opinion, this kind of self-censorship hurt him more than it protected him.
I could understand more if Bookworm were a vehicle for pushing a particular anti-LGBT narrative (e.g. in the same way that Atlas Shrugged is a political philosophy masquerading as a story). But it is not. The worst you could say about it is that the author is more socially conservative than is currently fashionable and has made some jokes that will age poorly. I actually think a lot of Japanese LNs are surprisingly conservative (i.e. much more supporting the status quo than subverting it), and that this doesn't really get discussed very much.
The closest thing I might be able to relate-to is the JNC series Sexiled, which basically depicts people like me as two-dimensional unsympathetic caricatures. There isn't a single redeemable male character anywhere in the series. That series is very much pushing a particular pro-female narrative (albeit humorously - it's part of the shtick). I imagine it would have been easy to take it personally and to stop reading in disgust. Indeed, looking through some of the Sexiled forums, I think there were readers who couldn't stomach it. But for me, although I occasionally rolled my eyes, I nevertheless pushed through and was rewarded with a silly, fun, and satisfying read.
Anyway, not sure if any of that is interesting or appreciated. Just my thoughts.
