Being a Marxist or Anarchist Professor in the US

I was talking to a Marxist colleague here on campus. We said that if were teaching in the US back in the 1940s or 1950s, we would have been harassed and persecuted and probably jailed, but that ironically you are safe to be a Marxist in the US these days when the enemy are Islamists.  I told him: if I have the same views I have, and I write exactly what I write on my blog but if I were a religious Muslim, things would have been different for me, and that I would have been persecuted.  Bottom line: it is safe to be a Marxist in the US (now), and it was safe to be a conservative Muslim in the US (back in the 1950s when the Muslim Brothers were tools of US foreign policy against communists).
