"You're not welcome." Flat out. Or people who hem and haw about "But I don't know how to describe [thing]! How do you expect me to boil down my Artistic Creativity™!" Or my favourite /s: "Blind people can't use the internet." Or people who think we can't enjoy pictures. I can when people try.

Even those with congenital, complete sight loss can enjoy things. They may not know what a colour looks like, but if you describe it properly... Just. The lack of creativity and the lack of care hurts. And the constant reminder of "You're not welcome" hurts more.
