People have goals. For example: I want to go the gym at least 3 times a week. I for example aim to study a langauge for 30 minutes a day. Reading is just another goal. Some people take hobbies seriously idk.

And how would you know the writing is bad if it is an unpublished book? A pretty broad assumption. If your not willing to admit the publishing industry has biases this is the end of the conversation. But it does, and this is why you see less POC authors in all genres and less female authors in most genres

If OP is a poc, it's exactly their place to comment their experience

Have you ever published a book as a poc?

They do, but publishers just don't want to publish it
