What is a "fujoshi" exactly?

I've been confused on this topic for a long time, since I enjoy reading bl and people considered that as being a fujoshi or fetishizing gay men. I had felt guilty about liking this genre because there are friends of mine that are in the LGBTQ+ community.

Just recently, I was browsing through tik tok and saw a video about what exactly a fujoshi is. The person in the video explained that the word might have been misunderstood in the west as just someone who fetishizes gay men. The term though, according to its actual meaning and history is basically just women who likes bl ( that includes everything including yaoi ). They were called "rotten girls" since mlm or the whole LGBTQ+ community at that period of time was considered "bad" ( or something like that ).

I know for a fact that everyone does not have the same opinions, that's why I wanted to hear what you think. ( also my recap of what she said is definitely not the most accurate or best so yea )
