But to elaborate more on what specifically happened. So I picked part 3 first... I watched it while being unsure if it was where I was supposed to start or not. This was in 2017. I finished part 3. It was alright I guess, but looking back on all the anime I've watched before and after that point, it's not my favorite by any stretch of the imagination. I then guessed which part came next, like I had guessed which one came first, both guesses being inaccurate. I ended up on part 1. I proceeded anyway despite it being obvious that it was in the past relative to part 3. I couldn't get past the first two episodes without getting bored of it. I dropped the operation until further notice. Or until... about a year ago, or at least a few months ago. I then decided to get my shit together and learn which part is which and what order they go in. I was willing to give the series another chance. So I tried part 1 again since that's the start of the series. I made it further, almost to the end of part 1 I think. I just no longer felt like watching it at that point as I had other things to do and other series to watch, it was at this point I realized jjba might not be my cup of tea if it had such a low priority. At least I enjoyed part 3 more than part 1, showing the series gets better when stands are introduced, though from my perspective, only marginally so.
The last point I want to make is that not enjoying the series that much isn't the only thing preventing me from giving it a third chance. I'm also reluctant to get into the fandom for a few reasons. For one, if I were a jjba fan, people would call me a gay **** sucker similar to how people already think I'm a lolicon just because I'm a Touhou fan. Joining these types of fandoms only subjugates me to more of those generalizations. Second, already been over how they're toxic. I'm already a bit toxic myself because of how the Touhou fandom assimilated me, but you already know there's several things I dislike about Jojo fans, so that's why I don't want to become one myself. However, if I do become a Jojo fan eventually and hypothetically it turns out the community is not as bad as I thought, then the other thing still stopping me is that I'm not that interested to begin with. After all, I didn't like parts 1 and 3, so how could I be a fan of something I don't like? Still, it could turn out that the rest of the series is better than parts 1 and 3, which I don't know for sure. There's still a chance I might try the series again someday because of that, just don't count on it.
