[Eren would just say that he would gladly die for humanity. Because he would. He has something to lose, too! It's not like he wants to die!]

Then maybe you should act like you know, and not keep talking like this is some other country.

[Yeah, so there. AMERICA!!!]

There are laws protecting mutants, and this is probably the best country for them to live in, so why do they keep complaining? Ordinary people are losing their lives, and mutants are taking their jobs, and the more mutants there are, the more danger humans are in. That's why they have to take measures now to protect themselves!
