School text books-infused agenda

If you think your professors are being out of line or unprofessional, college should be a safe place where you can address those concerns. I'd first talk to the professor in question, privately, you now, like adults in a professional setting would ideally handle this. There are professional ways to handle these issues in a class, if they aren't doing this, that's an issue. I hate to break it to you, but if I were currently teaching social studies in a public school in my state, it would be irresponsible of me not to discuss the ballot questions coming up in this election season, one of which includes medicinal marijuana, and another physician-assisted suicide. While I'd need to focus more on being a moderator and critiquing arguments students made in class based on validity and for the most part, keep my opinions to myself, if I were teaching at a college I would expect that with the considerable investment of time and money invested, not to mention peer vetting,  required to get to that point in my career would allow me to hold and defend an opinion in a workplace that encourages people to develop, explore and defend opinions.

Maybe you prefer a society that through social and professional norms discourages people from expressing their political opinions in setting other than ranting anonymously on the internet or grumbling at the TV when only their family is present, but rational,  enlightened, and informed adults should be able to have these discussions if they so choose regardless of setting. 

Which is ironic if you look at the historical development of academia.
