说句实话，工作中接触的加拿大人很多都特别自大，仇视中国

1.Apparently this is not the local traditional canadian's line of thinking.
Look at the post, though written in English, don't you feel that he or she is translating chinese into English?
Usually your mindset belies who you are!!!

2. Gui Lao (local westerners) they cannot really tell who are from HK, TW or Mainland.  Can they?  Can they tell the Mainland manderrine or Taiwan Manderine?  Can they tell the HK dialect?  This, too, Belies who you are!!!

3. SO you know who is the suspect now!  Do you?

4. Don't argue too much about it.  Though, Envy rots the bone, while as a mainlander myself, we have to learn some etiquette and have a good behaviour, which is very important to win other people's respect.

Just my personal views.
