A person's physical attractiveness should play no role in hiring, many people who are disabled might not be able to take photogenic pics. Those people are heavily disadvantaged, any person of color is heavily disadvantaged, I really hate the idea of social media creeping into LinkedIn.
For one it doesn't make a lot of sense for your political or social views to become a part of your employability. It's a resume not a statement on who you are. Then again I generally hate social media because it leads to the least informed shouting the loudest.
