Don’t Make Fun of the Disabled
Making fun of disabled people is not cool, and ramps and accessibility tools for the disabled are important. They have equal rights just like anyone else, and there’s no reason why some places would be inaccessible for them just because the architect didn’t bother to include a ramp. I thought that was something everyone knew, but I guess it wasn’t.

It’s pretty shocking that this architecture professor didn’t see the value and importance of accessibility ramps for the disabled. And laughing at your student’s work is never okay – even if you think their ideas are bad. All that being said, I’m reluctant to say this professor got what he deserved because losing your leg is not a joke (unlike, say, getting pooped on by a seagull).
