I agree about poker being a game of significant skill but try telling that to an elder. In some ways the same can be applied to all forms of gambling in that if you know how to, for example, read the form of horses then you can make a pretty educated estimation of which horse is more likely to win.
The problem then becomes one of semantics about how much skill, expertise and caution has been applied to make the likelyhood of winning a hand, predicting which horse will win or which team shall be superior etc. all but a formality and how much is guesswork, a punt or simply throwing good money after bad.
The WT seem unwilling to apply that logic to stocks and shares, where anything goes as opposed to what to the R&F is a blanket ban on any form of gambling. Except it's not quite.
Of course they have a point about the addictive nature of gambling, the harm that it does etc. but that does not prevent them from condoning plenty of other activities, notably the consumption of alcohol, that can be abused.
