I didn't read the OP as if someone was attacking but just "hostile". That could mean using words in a harsh manner.
Yeah, I see that could be the case. I try to allow for the OP being in Sweden and not fully familiar with conversing in English yet so I looked at hostile in relation to the rest of the sentence as meaning physically attacking, which would be one of the English meanings of it in a dictionary.
Either way, it is a topic worthy of discussion don't you think? Dealing with real life encounters and situations is where should display our Christianity and principles, IMO.
In any event, I do like discussions of this sort, to compare my views with other Christians views on serious subjects we have to deal with o a daily basis.
