That's poopy barrel scraping level of argument, all those things have social constructions that help them stay relevant, hell i don't smoke and abhor the nastiness of tobacco/cigarettes, but i'd happily pump my lungs full of vape, it's such a different league.
Please for the love of Maggie thatcher will someone argue a reason for why gambling should stay as is, when it clearly has zero social value? Animal abusing races aren't relevant in this context, as the growing trends will probably rid them from existence. You certainly don't need to bet on other games to enjoy them, and clearly betting on political probabilities is beyond the pale as it pushes gambling into a political abuse problem. Casino's are quite literally pointless wastes of land.
But pfft, whatever, i'll just wait for April to roll around and happily watch as the massive influx of high-street betting shops tumbles into the ditch.
