From google translate, I have checked all lines from -Dragon- and I do not see any insults. Interestingly with your second translation (with symbols included) they do come up as insults. I understand these have different meanings. Since -Dragon- said "dit me may thang ngu" (google translates to I'm sorry) and not địt mẹ mày thằng ngu then I would assume we would go off first meaning (what -Dragon- typed).
All the others I don't see any insults about family or insult at all.
Rejected and Closed for now.
