People also excuse too much cultural egocentricity on the pretence that their own culture is naturally congruent to a morally advanced standard of living - both expressing and (by default) conforming to "basic international standards of freedom".
Regarding alcohol consumption specifically. You all live in countries that place all manner of restrictions on consumption and use of various controlled substances. The exact substances vary from country to country - there may well be some that are controlled in your own country that are freely used in Qatar for all I know.
The exact means by which religious views propagate into legislation and enforcement is another area that's both divergent and widely misunderstood.
Also, there's nothing explicit in the UNDHR on alcohol so I'm not sure which "basic standards" you're referring to. Stringent controls on alcohol are certainly not unknown to the supposed bastion of freedom, the USA.
