LOL it was not "nothing wrong"
He supported the aggressor, the one who kills, murders, and rapes people of the girl's nation he was talking with.
Of course, it made her react.
No wonder your people do not understand it, as you are far from the values of normal people who understand that it's not OK to attack another country just because you think you can.
And this is what an idiotic "out of politics" position can do to a person. Maybe Braveaf is a nice guy, IDK, but his views on things were a result of the culture around him which made him think that really evil things are normal. That's why you gotta educate yourself and think critically, learn things around you and history especially. It will help you stay out of trouble, especially in the modern world.
This "out of politics" position is made to fool and manipulate people. While politics is everywhere you want it or not, and it's something that influences your life.
Be clever and support good things, respect other nations, and don't be scared to speak about evil things. This is how you fight on the good side, not the other one. Evil only rises in silence and ignorance.
