Wow, seems like there's a lot of heated discussion about some of the later elements in the series. I'm not going to tell anyone that they shouldn't talk about this stuff, but I just don't get why people in here are so hostile to this one specifically.
To be clear, I hate forced social commentary as much as the next guy. There are many pieces of media throughout the years that have been ruined because someone wanted to shove in some sort of social justice plot-line that resulted in breaking the story's narrative completely, or, in some cases, made something that was never good and demanded that people see it as good 'cause social issues (See Captain Marvel, Batwoman, ect). I'm not going to call anyone here bigoted 'cause I do get the base sentiment. Stuff like this can be a problem, and it annoys me when it happens. Partly 'cause it ruins potentially good stories, but also because I think it betrays the very message that they want to push.
But people are reading way too far into this one.
I honestly wonder if some people here have read the WN or LN before complaining about this stuff.
@BugDemon and others are more on-point with the reading of the original novel in that most of the developments within the story feels adequately natural. Not once did I ever feel like it was being shoved down my throat, nor did I feel like the plot was being thrown by the wayside to exposit something that seemed irrelevant to the plot. They all felt like fairly natural progressions of the plot. Does this novel have some issues surrounding this topic? I would say yes, but non of those issues are for the reasons posited by some of the people here.
So, my recommendation is simple. Read it yourself before you assume this sort of thing. Even when the series does get more serious, I think there are plenty of people here that'll have a really good time with it.
