It’s a sad video. You must sympathise with anyone who feels so intimidated by anything.
Ensuring that anyone who chooses to live in a new society respects the traditions, culture and people whose society it is, must be a basic responsibility of government. I have long argued that anyone admitted here should be made to understand, and accept, that any transgressions, however justified will result in their visa, or asylum application, being cancelled and then returned.
We have made steps towards this. The “Life in the UK” test is compulsory. There are more returns than many realise. Whether that’s true of Germany too, is unknown.
However we aren’t doing nearly enough. Both at the time of entry, when every new arrival needs to know in unequivocal terms, what’s expected and what the consequences of breaking them will be and in following up.
Having citizens frightened to walk the streets is unacceptable whatever the cause might be. That they might then look to the far right for a solution ought to be sufficient motivation for any government to take action.
It’s not unusual. I lived for a while in the Philippines, where corruption exists at every level of society, where you cannot trust the police or the courts. The unwary get shafted. Kindness is perceived as weakness in business but is ever present at a personal level. Foreigners like me were left in no doubt that we had to comply with those standards and never to challenge them. Do so and you were on a plane home very swiftly.
