You might be empathic in person, but you did not compose a reply that evidenced individual empathy, just acceptance of a potentially empathy-driven outlook.
And as ChatGPT-3.5 says when asked whether your original reply is plainly-worded or combative, "Overall, while the passage strongly advocates for its point of view, it does so in a confrontational and assertive manner, making it less plainly worded and more combative in tone."
It's fine to be forceful with your comments, but you should be prepared to own up to the degree of rhetorical intensity that you deliver.
