I simply mean being vigilant with interaction between my children and others

To be honest this is something what I’d expect to hear from survivor who hasn’t processed their trauma. I’m not trying to tell you you’re wrong to be vigilant, but to me this reads like a subconscious cry for help. I might be totally wrong, in which case I’m sorry.

watch interactions they have with people like a hawk,

This seems unhealthy on your part. Like paranoid or smthing.

Please note that Europe isn’t as prejudiced with Muslims as it could be.

The answer is impossible to answer until you tell us more about your needs. Better choice considering what?

In general, untill you have terabytes of data or a significant amount of traffic (operations per second) database choice does not matter and you should be using cheaper option, where the cost should be assessed as a derivative of price of hosting, cost per operation, cost to deliver (how familiar you are with it).

When you have significant amount of data or traffic - only then you should worry about database kind or language. Until then this could be a premature optimization.

Dprk?

What is your point? I’m honestly asking, not being sarcastic.
