RE: How Do I Respond to Anti-Hunting Comments
Maybe it wouldn't hurt to admit that "yea, I did feel a little bad about it, the deer is a very beautiful animal, and killing it was an intense act, but at the end of the day I felt good about it because I took some nutritious meat, and I realize that hunting is necessary for the deer and for their habitat."
A short answer is usually best in response to a flip remark.
Here's another approach, or could be added to the previous remarks: "No, I didn't feel badly about it, I'm sure that I killed the deer more humanely than any natural death would have been."
