Is it really that bad looking like harry potter though?
"When we encounter insults from other people, we must deal with them with reason rather than anger. Either the insult is true, in which case we should be grateful for the insulter for pointing out this area in which we could improve, or it is false, in which case we should pity the insulter for his lack of accurate perception. Either way, an insult is nothing to get upset about.*"
People often say I look like harry potter, I am a thin white man who wears glasses, so that is a reasonable observation I guess. I never have wished to not look like harry potter, of all the ways to appear it is an acceptable look, I could look less like harry potter if I cared to do so, but I see no reason to look unlike harry potter.
I think /u/gary_oak has a perceptual problem in not accepting his resemblance to harry potter, it is okay.
