Manga is another powerful medium to express something. It doesn’t have to always be fantasy for self-indulgence. If you don’t like politics, then just stay away from them, there’s so few manga about them anyway.
However, I don’t think this is an issue people should ignore about. It’s not just “an agenda pushed”, we are talking about the CCP here. People tend to think that the problem is far away and unrelated to them, so why should they care? But I feel like with China, sooner or later you will be involved. Trying to “escape reality” isn’t gonna help much with that.
