Very interesting and a sign of the times. It reminds us to be careful judging how people were in different times, even though we need not accept it, and we can use that to shape behaviors today.

BTW, I loved the Tijuana Brass albums as a kid and they inspired me as a young trumpet player. I knew that Alpert was average as a trumpet player (no Miles Davis or even Doc Severinson), but he did have a huge impact on music culture. His rock and roll descendants include Blood Sweat and Tears and Chicago.
