Smoking should not be made illegal inside all other places, and especially not inside pubs, bars and cafés where people go to have fun, because it does not cause direct harm or defect to anyone or invade anybody's rights like many people persistently tend to believe, and because entertainment itself must encompass the maximum amount of possible and available freedom.
Smoking is a free, recreational activity left to individual discretion, that should be beyond the scope of the law according to the equal rights that we all have. It is not a legal matter by nature, it is one of our God-given rights and must be respected by the law of each and every country, as should also be free to practice wherever, whenever.
Many people fail to realise that prohibiting smoking where not necessary or where not dangerous also affects them and their rights just as everyone else's, whether they smoke or not.
Many have shown phenomenal intolerance in this way to another social group and quite sadly isolated it and abandoned its existence, but society must accept all its members, demonstrate solidarity in between them and not behave in an imminent way towards a certain group of people, as this group of people has a special concern which definitely cannot be isolated by the legislation that currently exists.
Let alone the fact that it does not carry the weight of equal importance to be smoking somewhere where it would be dangerous or harmful, as compared to everywhere else where it is also punishable under equal terms.
