It's hard for someone who has gone to college in the last 20 years to believe, but the faculty at A&M, and nationwide, was infinitely more conservative in the 60s and 70s than it is now, and not just in engineering and business and so on. The winds of change were stirring--there were progressive and even radical professors at Texas when I was in grad school in the mid 70s--but the tenured faculty were quite conservative, in my experience, even in English, History, and American Studies. There was NO mention of "race, gender, and class" in a single undergraduate or graduate class I took in any of those subjects. No "queer studies," etc.
But as I said, change was coming. I was a TA for a class called "The American Experience" which was taught by three professors (one in English, one in History, one in Government) who had a fairly liberal take on American history. (The students called it the "What's Wrong with America" class.) One of them was a real radical--he had participated in the Chicago riots in 1968. One of the books we taught in the class was The Grapes of Wrath, and the professors had to justify it to their higher-ups every semester, because the department heads and deans all thought it was a Communist tract. Not kidding.
