Such outrage is counterproductive, reaction just provokes them.
That said, IIRC in that terrible video game published by nuWolf last year, there was some refugee related content, so I don't see anything inherently wrong in having Mexican refugees instead of Syrian ones.
And their portrayal depends entirely on ST.
I also hope that no one here subscribes to nuWolfs antinazi policy>“Unless you are a Nazi, or a neo-Nazi, or a member of any other hate group that uses these disgusting philosophies to advance your hateful agendas. If you are a member of one of those groups or support those agendas we don’t want you in our community. You aren’t welcome, and if we find you spreading your hate in our community you will be shown the door. We don’t want your money. You can keep it.”
I hope we are better than this here, 4chan is inclusive as it is possible long someone doesn't willingly remove themselves by being "offended".
