Why do people hate this arc? Is it the goblin rape that's bothering you or the gore? Because news flash, both of those themes aren't gonna magically go away once this arc is over lol.
Also, imagine if we all had to wait a month for GD just to drop one chapter.
I'm fine with the goblin rape and the gore.
I just wish the goblin rape had more impact, like if you actually knew the girls.
For example Into the Deepest, Most Unknowable Dungeon there is a group girls that get captured by orcs and get made into seedbeds to get raped repeatedly, it could have just been a one and done thing but you get like half a chapter or so every few chapters focusing on the trio so you slowly get to know them.
Don't read it though, the manga is pretty shit and the only reason i am still "reading" it is because of those three girls and their situation.
Another example is Ingoshima where you get to know the girls after they get captured and raped by those native island dwellers.
Here you don't really get to know the girls they are either there to get fucked by the MC or they are there to get raped.
Atleast they get a name if they get fucked by the mc in the future i suppose.
Tl;dr the rape lacks impact to me
