The thing about twitter is that if someone agrees, they tend to just like a tweet.
If they disagree, they reply (usually rudely tbh). So it creates this massive negativity bias as a user where it feels like everything you say is hated even when its not.
I might also change my opinion once everything is said and done. Or i could change my opinion after hearing others perspective on it, maybe there is something I don't see yet. I could love it after the next chapter, it all depends on how Oda handles it next.

I think it's important to not be reactionary to these things but still have thoughts about the current events.
