Humans [and some ghouls] think that ghouls and humans have a parasite-host relationship. It makes it harder for Kaneki's wish to unite humans and ghouls. I'm really anticipating what will happen to the next chapter.

I've been reading the manga since the first era till the :re but honestly, I haven't watched any episode of the anime. I guess slow internet connection is a partial reason.
