Good job it is subjective otherwise who would decide?
Che, your picture is plain, but to me it isn't downright ugly, so you have a much lower "Ugly tolerance" than I do and your judgment would condemn a high proportion of the human race to Ugly
I occasionally meet one person who I find it really difficult to carry on a conversation with, as their physical appearance repulses me. This surprised me at first as I had never experienced it before.
It doesn't get easier, despite that person being a decent person. I am ashamed of my reaction, but I guess everyone has their limits.
