The fluency of their English seems to vary a good deal. Some are beginners and others are at levels I can't even tell how good they are. I'm not such an ambitious learner that I only check the beginner's question threads.
I don't think it's necessary to learn English if you're living in Japan. But when you happen to see the people using it, it sometimes makes you wonder "what if I could speak?"," What if I could write and read?"
In your worlds of simpleness, the motives behind my actions and choices are mercilessly simplified or altered to fit how you want to characterize me. I tried to explain them as they were twice or thrice but couldn't get my points through to you due to my lack of brain. I was surprised when I found out that you still took those words as something despite my attempts to discourage that. So I also had to resort to simplification to make my points clear. Sorry about that. And sorry for having been misleading. You have already decided how you want me to think in your world and will intend to keep building up your confirmation bias against me. I can't do nothing about that. You are probably right about me being unlikeable. But you are wrong in some details.
