I don’t know why people can’t talk friendly

Why people always choke others instead of talking friendly? I couldn’t understand. Once I saw a beginner’s map (maybe?), and he/she’s building a really long railway but using metro. I just reminded him/her that using high speed rail is better for more points. You know what? He/she just choked me like “Hi Kobe. I didn’t even notice that metrodreamin is some sort of game or competition. ” Actually I was shocked then sad then angry after I saw this. But what makes me so hysterical is that he/she even blocked me! Ok, I shouldn’t have reminded you that, it’s your choice, maybe you have some mArvElLOus thoughts. So that’s why you choked me and blocked me? It’s ridiculous! Someone friendly reminded you and you commented like this? Then no one will remind anyone and the whole civilisation won’t be able to advance! If you really disagree with my suggestion, you can just ignore it. It’s your choice, no one can change, including me, unless you accept. If you don’t accept, you can ignore or thank me and say no. That will be more friendly. Ok? That Is Disgusting So Pls Stop Choking Others * P.S. I’ve emailed to the officials
