The person is adversarial, that is clear in their comment. There's literal adversarial quotes like "only do X if good for you, otherwise do the opposite". On the other hand you went straight to googling a random commenters job and attacked that.
Every one of your sentences is an assertion presented as fact. That could also be considered adversarial. GP has replied in a constructive manner in the meantime btw.
And yeah, no googling involved. I often look in HN profiles to find more context to why people are writing what they write. I don’t stalk them, tbh I find it creepy when people from HN find me on X and DM me.
