He's not really advocating racial profiling or one based on nationality.
I mean if a muslim pakistani or muslim arab guy came to the airport looking like this he obviously isn't likely to be a jihadist.

And right wing extremist groups do carry out terrorist attacks but not as frequent as Islamic terrorism. So it's not an unreasonable thing to say that someone who looks like a practicing muslim by his dress, behavior should be profiled. Besides a huge proportion of practicing muslims are not moderates and they often hold extreme views even if they haven't committed a crime themselves.
And once again he said that all people should be checked throughout it's just that
fundamentalist muslims are more likely to be terrorists than any other religious group and it makes sense to pay a bit more attention to them at the airport.
I agree with Sam Harris that people are being waay too politically correct than necessary.
Note that I mentioned that fundie muslims shoould be profiled where as the sharukh khan type muslims should be checked as well but there not as likely to be terrorists.
