Wanted to correct one part of what you said: The thread is not exclusive to Brahmins[1]
I know people who identify as Kshatriyas and Vaisyas wear it. It is just that almost all brahmins do it and the practice has reduced or stopped in the other two varnas.
And from what I see, he didn't compare the thread to burqas. He compared the calling of the thread as sign of discrimination to calling the turban as a sign of terrorism. There is a difference.
