What a stupid comment!!!! It's nothing to do with making a ridiculous stereotype of westeners maturity.
I'd suggest it could be one of two things; firstly it could be a cultural thing, Western people tend to be more vocal about how they feel about something, we don't have the same 'loss of face' that you may be accustomed to. If it's this situation, it really is just a slight raising of the voice and expressing a bit of annoyance at something. For westerners we find this very easy, because if someone is vocal at least we understand that there is a problem, and then on the same note it is unacceptable to sulk and keep a grudge. It's a case of saying what you want to say, and that being the end of it. When this is the situation, it does take a little bit of adjustment with both parties. Westerners living in the Philippines, tend to resign themselves to accepting when something is wrong, because it can be difficult in the culture here to express your annoyance and dissapointment without offending (thats a cultural adjustment).
So, what i'm saying if this is the case, talk about it and try to understand it from both peoples side.
Now if its something more aggressive, where the person actually has an anger management problem, and it concerns your safety and wellbeing or you feel it's an unacceptable environment for your children then i'd highly recommend professional advice.
