It's not dialect or racial issues, lots of other threads get
removed or posted to another non relevant forum. 
One such thread is the one about LHL commenting on NS for new
citizens.
There are many more post being moved to other forums at the
protest of the original thread starter, but it's turned a deaf ear
on.
Imagine LHL commenting on laziness or mollycoddliness of
Singaporeans and it gets moved to Slackers Forum.
But then again who can we trust on defending singapore?
