Well, there are those claims of unwarranted scrutiny and his assumptions that they were race-based... and then there are his bogus claims about what was said about him in the media and before Congress, which have been documented.

You misinterpret proc0's comment: they are saying there is no excuse to treat Neil deGrasse Tyson as a shoplifter because of his race, that there is no excuse to ever decide that all people of a certain race or any category are all something or share something (in their comment "assholes" in yours "shoplifting").

Basically racism (using this definition: [1]) is never OK, regardless to which race and with which attributes.
