It isn't relevant to the original comment which was basically that Europe and Australia should not take any Syrian refugees.
And while it is true that the refugee convention doesn't provide a right for asylum seekers to choose their ultimate country of resettlement, it doesn't force them to stop at any particular point either.
In any event, where should they stop?
In Jordan or Lebanon or Turkey which are overrun and where conditions are intolerable and unsafe?
On the first tiny Greek island they encounter, which can't possibly accomodate them?
In Hungary which doesn't want them?
It's all very well to criticise them for wanting to go to Germany but Hungary has only allowed them into their country because they will continue on through Austria and Germany will accept them.
If I was fleeing a brutal, savage civil war and inhumane conditions in refugee camps and desperately seeking safety for my children I wouldn't stop until I actually felt safe.
It would be hypocritical of me to expect them to do otherwise.
Interestingly I love strong black coffee and dark chocolate, though I prefer wine to beer.
Research which asks stupid questions often finds stupid answers.
