Reading the GP again, it doesn't seem snarky. They are just stating what they believe the definition is.

It's very easy to read emotion into an emotionless format like text. Which means it's very easy to devolve the conversation to anger very quickly.

From that perspective, you also read emotion on my emotionless text. I was also just stating what I believe the definition is, with no more or less information than the comment I responded to.
