Invisible Man aka a book full of lies

Honestly, I do not like Invisible Man so far. I do not like it at all. You know how theres that idea that you might not be able to believe like anything a first person narrator says? Yeah, I feel like that totally applies to this book. Also, before we really get into that, there are some parts where its just seemingly pointless metaphors after metaphors and it feels like I could just skip four pages and still know what was happening in the story. Like with the blind guest preacher who was giving a sermon about the founder (weird). He was just talking and talking and none of what he was saying about the founder seemed important at all. Okay, back to the real reason that I dislike the book: all of the lies that I feel like this guy is telling. The biggest thing that I have felt was complete bs so far was the boxing match or whatever the heck it was before he was given a scholarship. Things like that do not happen in real life and I highly doubt they happened back then. not only was it so unbelievable, but there were also some inconsistencies with his descriptions of the other 'boxers.' At first they were giant thugs who were so angry that this little scrawny kid had made their friend lose his job. Then they were all very scared and worried right before the fight, as if they did not know what was going to happen. How could they not know what was going to happen if it was their job? Also, the way they all vaguely knew how to fight blindfolded and they all knew not to touch the electric rug too much also suggests that they had done it before. That electric rug though, like what the heck??? The way all of the white guys were attacking them and throwing them on the rug?? That just did not seem plausible to me at all, also why the heck would the school superintendent put him through all of that and then be like "oh yeah I totally respect this kid and I want him to have all of this money even though he almost got beaten up when he said something about equality." That entire part made me completely lose faith in the truthfulness of this narrator. The next dumb part that I totally think is unrealistic is the whole deal with Mr. Norton. Like firstly, why is there a mental hospital on the school campus/close to it? Why do they let all these men roam around freely to drink and have sex with whores? How am I supposed to think that this actually happened? Maybe I have unrealistically positive beliefs about the world, but I really just cannot believe the way that Mr. Norton was acting/being treated, the way all of the men were acting, the way the bar tender was acting, the fact that whiskey apparently cures illnesses, the fact that incest is super interesting to white men, etc. Just all of these things so far, I just can not believe any of them and its making me just really not want to read the book and thats a major issue, so come on mr nameless narrator, make your story more believable!
