I feel bad today

A couple of hours ago, I stumbled upon a digital drawing of a woman with a big nose. The artwork wasn't bad, imo.

When I looked at the comment thread beneath the it, I found several comments mocking the artwork simply due to the artist's drew a woman with a prominent nose.

I then told one of the commentors that their joke wasn't funny. I don't know why, but I felt guilty and nervous afterward doing that.
