Before I start, I should mention that the closest thing I found here was this post, but the comments say something I really want to avoid, which is to sound like a [political ideology here]-nut.
I am enrolled in a undergrad degree in Brazil called "Comunicação e Marketing, which I believe translates to Communications and Marketing. In any case, this degree focus mostly on the marketing side, but we still have to learn some theory first. I love it, but I feel like I'm having some issues at the moment.
I have been told both by my professors but also by people in Humanities that we're basically being critical all the time about what happens in society. Right now we're talking about the impact of mass media on society in class, with positive and negative examples.
Whenever I try to study something within this field but not mentioned in class, usually more "recent" things, I'm bombarded with terms like "decolonize this and that", "Global South", and something related to Chomsky's work.
My question is how to approach certain topics from a certain POV that denies what the professor is saying?
Whenever I want to give a counter-point to what is shown in class, I have a hard time finding academic sources that aren't totally wack or associated with the far-right. I rely mostly on what I have experienced or seen people talk, rather than quoting a theorist in this field (or adjacent fields like sociology). I'm not sure if this 100% frowned upon, not recommended, or I should be more careful when doing it.
Are there better ways to search for content in the Humanities? I pretty much just use Google or use some of the references on Wikipedia to see if I find anything useful.
