its not sam leong,their styles are vastly different.sam leong is highly racist and discriminatory against many races,john tan doesnt do much racism and is pretty neutral except against sinkies,sam leong likes to reply many sentences with PAP is the best,john tan doesnt do that,sam leong's logic is rubbish,john's logic is better,sam leong loves talking about success and whatnot and use it in his pro PAP arguments,John no.
its clear they are two different people,human characteristics are impossible to change/hide.their individual bias and prejudice will show up sooner or later.
