Is this street justice? The "manifesto" of this forum is freedom of expression - except for some understandable religious or racial restrictions. Ask Sam. He as a host is supposed to uphold this basic rule.
How can you ban someone whose opinions are different from yours - even anti-PAP libel suits go through the proper court procedure? Has he violated any rule?
Sam has to make a stand - before this forum goes into one way track anti-PAP, anti-Singapore forum. Then you don't have to ban some forummers anymore, they will simply delete Sammyboy shortcut from their favourites!
