People are the same where ever you go.
To pass a "Absolutely cannot stand Singaporeans" statement makes me wonder why he is here in the first place.
By passing such statement, it could reflect one or more of the following:
1. His immaturity,
2. His poor command of the language (perhaps he didn't understand the meaning of absolutely),
3. His poor racist upbringing (parents and/or school),
4. His lack of balls to walk out of this intolerable place since he absolutely cannot stand Singaporeans
5. His lack of understanding of how such posting could affect him and his family if it went viral. :o :(
