I'm gonna pretty decisively say "no".
By the very nature of memes, you don't know if they are talking about real events or just joking, you don't know who created it or their biases, and you only get an EXTREMELY simplified perspective & information. You are also limiting the news that you see, maybe missing out on something important in favor of something funny (not to imply that we should maximize the amount of news we see).
I disagree with your point B about memes, that they don't ask you to pick a side. I feel like memes are often more biased than traditional news. Even in cases where news is extremely biased, you can be aware of the bias and judge them consistently because they are not anonymous.
