Sometimes people snap and break and hurt those they care about under immense pressure. That doesn't mean they don't care for them, only that they've reached their limit and have lashed out wrongly. That happens in normal life, let alone people who have trekked over hundreds and thousands of miles to try for a life outside of war and destruction.
But even so does he reflect all refugees or indeed most?
I'd say he almost certainly doesn't.
So why do you keep bringing it up as the be all and end all for these refugees.
Did you watch the video of the refugees refusing food and water?
They
all, together, threw the water onto the tracks. At 1:36, you can see a child accept some food from a female officer. The men then come along, shut the windows and tell the police where to go. The male refugees are willing to let their wives and children starve just so they can get to Germany, because Hungary "isn't good enough."
I'm very confident in saying that when all the refugees on that train are acting together, that they reflect all the refugees there.
