I think your response pretty well outlines the response of the students. Misplaced outrage flowing over into matters that the outrage isn't relevant to leading to crazily reactionary responses that only serve to make your point less likely to be understood, accepted, and engaged with.
This person has actually made a few points regarding the overall reaction to this (the article itself constitutes a reaction) and you're simply dismissing it based on tone. While Hubski encourages civil discussion, you're straight up ignoring his/her perspective. That's called tone policing, and your condescending reply is definitely not helping further discussion.
oh please, fuck off. racism to you is a "discussion that needs to be calmly discussed" racism for me is the shit i have to deal with daily. swap places with me and lets see how it goes. or not, because you probably couldn't fucking handle it. jesus. "my point." this place and the rest of the world are never going to change. must be fun being the default.
