To be very frank, this is definitely not the first time I have seen people forget the difference in cultures on this forum. As someone who had been fully accepted in two very different cultures and as someone who grew up in a multicultural household (that had the same struggles as every multicultural household does), I do believe that many people verbally say they understand that cultures are different, yet do not fully understand what that means. (Note that I am not blaming anyone.)
What is reserved in Western culture is still quite aggressive when viewed in other cultures. I know I now find most Americans (a group I was/am considered part of) to be incredibly aggressive. Yet when I code-switch, I realise that, in an American context, that American is actually quite soft-spoken. But in my current context, they come off as very brash, arrogant, and aggressive.
I myself had to change completely. Quiet, non-aggressive American Me still came across as aggressive when I first started assimilating into my non-American family's Me. I had to completely change my mindset (American Me has different values, politics, mannerisms, verbiage to Singaporean Me - so much so that I struggle to vote because the two Mes would vote very, very differently).
I even struggle to communicate now with my American friends because of these cultural differences in how things are phrased, what is acceptable to say, what connotations are implied/read.
TL;DR
So yes, to OP, it was aggressive. To the Westerners, it was not aggressive.
Both are equally true and valid. It just depends on if you want to speak in a Western style to a non-Westerner, or if you care to speak in another way.
As an American that deals directly with a team in APAC including Singapore, Thailand, Malaysia, PH, and Vietnam I have to be very careful with my wording and approach things differently. We conduct business differently and understanding the cultural differences has made me far more successful. It is so easy to come across as rude or aggressive without meaning to!
