"I just know you guys will make fun of me."
Of course I will do you know how stupid you sound right now? I just had such a good laugh after reading this because, really, how can you say this and be so serious about it at the same time, my gosh! Are you sure you are not trolling???
Anyways guys, this is a good time to remind y'all to not bring your own social-political views, especially when you know that you're consuming media from another country that clearly has different beliefs (you said it yourself: "To top it all off, mc is Chinese !").
"Justice" is a powerful word - one of the reasons is because it can mean something SO different to all of us. Now, I will proceed to answer the question you've posed: "If you don't protest eating meat, what right you have to talk about 'justice'?" The answer is so simple it will blow your minds: because you and FX have different views of justice, and perhaps neither of you are right! Now if you know this, then what is the whole point of having this immature rant about FX eating meat. So what now that we know you have differing views on the moral righteousness of eating meat? It means nothing! (surprise, surprise)
Also, you suddenly have an extremely random topic shift to power: "But I wish he believed that without "power" he can't change sheet." I am almost certain that he knows this to be true above all, if you've watched the 2nd season you should know (remember the imperial exam arc???) The story goes that he initially didn't want power because he didn't have the same grand ideals as his mother. But now that he's seen the world and wants part of his mother's ideals to "come true," he knows that he'll need the power to make it happen.
So is the "hypocrisy" in the room with us? Everything you've mentioned is either due to differing fundamental views or completely inaccurate information. I suggest you rewatch the show.
