Several companies I've worked at, if this guy knew his stuff and was able to do the job well, they'd give him a position no problem.
Considering the amount of anti-racist education out there, that we've all learnt to grow up and not judge people in the corporate world by their skin colour, race, creed, sexuality, or disability, it saddens me to see how many people just reject someone on the basis of how they look.
What would you do if faced with someone highly skilled, maybe more skilled than you, who just happens to look different? How is slagging this guy off different to being racist?
