Because we all have the ability to research outside the course. Yes, the lecturer may present things in a certain way, but we're all independent thinkers here and we all have the capacity and resources to look into the issues if we think there's a problem with bias. There are also methods like course feedback where you can make such comments (and those things are read by higher powers it's a formal and legitimate system and feedback is taken into consideration).
So what if people laugh at a conservative joke? Lots of people laugh at how ridiculous extreme left ideas are as well. Doesn't prove your point or mean anything in particular.
And some subjects definitely have more of a leaning towards a political affiliation than others. It would be really weird if my Intro to Logic subject had a heavy political bias because it's just not relevant or applicable. By the same token, it would be strange if my history subject didn't have any kind of bias because part of what we deal with is how bias and society influences how we perceive the past and context etc.
Just because there are posters around doesn't mean that everyone believes that. Eg take the strikes which one would typically think was a very 'leftist' thing, yet not many students choose to partake in them, or picket, or rally. Posters just mean they have a dedicated team of people who have the time to poster. Next semester, you'll probably see a lot of EU posters around, but that doesn't mean that everyone on campus is a Christian. The point you're making here is completely unfounded.
As I said earlier, my experiences has been one of critical thought. I've only experienced lecturers giving very balanced approaches, or when appropriate, acknowledging their own bias and explaining why they hold that view. I can't speak for absolutely everyone's experience though.
What I don't understand is why you're getting so riled up about this. If you're worried about it, just don't do an arts degree. Doesn't seem like it's for you.
What I'm trying to say is that these jokes are indicative of the general uni sentiment/ predominant ideology, not institutionalized sources of leftism
Yes, subjects based on science can't be ideological - I'm referring predominantly to cultural/ social studies - english lit, philosophy, economics (pretty sad economics isn't impartial anymore), anthropology etc - But the question is, where do these courses lean toward?
You're actually trying to tell me the arts faculty as well as its cohort (and to a degree, the entire uni to a degree) are not predominantly socialist? If so, I think you have some serious misconceptions about academia as a whole - Ever heard of the Frankfurt school? Where do you think 'critical theory' came from? Postmodernism? Why is there no unit on Austrian economics or libertarian-ism?
The fact is that here and now you prove my point - I point out what seems to me and many others (who aren't idealists) a very real and present issue and I'm criticized for being unfounded and absurd - Unionship used to be COMPULSORY and is still a large faction of the uni; if that doesn't speak ideology to you, I don't know what does
I'm not riled up, I'm simply trying to spar a discussion and 'critically' think about the culture of a university - if that's wrong and I should suppress potentially real issues, I don't want to think about the culture of the uni itself. Also, to your standards, critical thought and discussion, I think I'm more suited to an arts degree than you'd think.
But then again, ain't nobody got time to flip burgers
