I actually visit Reddit regularly for that. I don't have any other social media, and I don't even have a reddit account. I just go to the front page and scroll to see what pops up. The top voted comments usually have a good trail of sources, including opposing views. The r/Conservative and similar subreddits really give me a glimpse into the other perspectives, although I have to say it makes me understand where they are coming from even less. The most evident thing is how they have very narrow sources of information and basically reject everything else.
