Quarter is not that much. That means there is more that is not isekai. So whats the issue?
It sounds here that you are complaining that isekai even exists. There are people who want that stuff. Leave them to it. Things not isekai are being made and you are not forced to read isekai.
What you're seeing is how the Right eventually comes to accept things the left push for and how the things the left push for become normalized in society.
There is a meme that the future republicans will be all for drag kids and trans kids and that these things are conservative but will oppose bestiality until they eventually accept it while the left has gone even further left.
These people view "The right of people is to exist, to pass down generational knowledge, and continue the family blood line" as nazism and fascism.
Hell, they are even statements like this:
" It�s about not-becoming because the notion of becoming is perceived as following the capitalist logic of production and models of success that are often tied up with colonialism. It asks, why the fuck should queers be nice? And asserts that politeness is heteronormative and we should embrace our utter failure at functioning within a colonialist, heteronormative, capitalist, racist, sexist and transphobic framework."
Depending on how extreme they are, civilization itself is nazism and must be torn down.
Worthless tradcucks: Just work harder men. Pull yourself up by your bootstraps!!
Same worthless creatures agrees to hand over everything to women.
Here is my question.
Why is it that everyone who considers society to be against them like women or black people or whoever allowed to call out society and demand changes but when men do it, they are derided and called incels?
Why do Men have to punish themselves to cater to women and society? Tell me why when society never makes these same demands or women and just bends over for them.
Society says that work hard and pull yourself by your bootstraps is bullshit but only when it comes to certain groups. Men still have to adhere to this.
Thats your problem then more then isekai.
And sure, isekai, lots of it is same tropes over and over again. I agree with you there. But that doesn't mean it has no right to exist if people like it and want it.
It just has to not be the only thing around. And it isn't just by your own post.
Look, isekai is just a trend just like how moe was a trend and it seemed like everything was moe but eventually anime and manga moved on.
