I'm sorry, so very sorry, that I did an insulting to you in that gerrit patch page, my brain couldn't control my hand in that time. I also promise that in the future, even if such -2 happened again, I either don't pay attention to that, or if that affects my UI experience, I will try to persuade the corresponding developer team(s) on Phabricator or public discussion pages such as VisualEditor/Feedback. I kindly know that unlike Phabricator, anyone's comment on gerrit can't be removed, and may make one untrusted.
