I'm not sure what motivation you have for highlighting someone's skin colour as you mock them online - it's not a common thing for people to do unless they are using it as a racial slur - hence his words in response.
Not everything has to be taken in the context of race.
I would not be speaking about 'race' unless you yourself had brought it up in the initial comments, so from my POV it is you that has made this about race in some way.
If you want to contest him not being all those traits, I wouldn't go down that conversation. The succeeding conversations in HW had nothing to do with that and he nitpicked one line to make a big deal of his narrative against HW. If I'm called an Asian Grown ass man who gets upset of negative emojis, I would contest the negative emojis part because that's the only thing that isn't a fact when I said there.
Again, whatever spins the narrative to make his case, keep enjoying the drama. The guy accused me of being part of HW when I'm just there on the server just like anyone else with a role that allows me to post gif images as a privilege and nothing else. He said he has been observing for days yet still couldn't figure out I'm just like anyone else there.
I'm not enjoying anything in particular here, I have much better things to be doing ;)
I am not contesting what he might be 'racially' defined as in standardised human reality. I personally have no interest or even a belief in 'race' at all, I see humans and before that I actually feel spirit moving in human forms. However, people do love to stir up drama and attack each other based on the imaginary construct of 'race', which you seemed to be doing - so I am just enquiring why, that's all.
You're indulging yourself in the conversation long enough that makes me say otherwise. How he took those facts about his physique and commentary about his attitude towards negative emoji is the sum of my observation. I would admit fault if he does not identify himself as a adult man, caucasian and isn't upset about those negative emojis.
