Doesn't China do similar? They make a social profile of a citizen based on their social media profile.
I do think it should be taken into consideration but not the final say. For example if my friends were all white supremacists I would expect others in real life to also have issue with who I hang out with.
That said there is also a big difference between white supremacists and people who disagree with the US government! The latter is not necessarily an incorrect stance to have in this day and age.
That said, something like going to a well to do University for education should generally outweigh the bad.
