Thanks for the OT political advice, mick, but you'll find that "propriety" here is best left to the opinions and actions of the moderators and admins. If you have a problem with something, it is their preference that it be taken up with them, not between members.
What international cruisers may not be aware of, is that Americans have varying rights, obligations, duties, and viewpoints that may be radically different from those of other nationals. We are in some cases legally bound to "promote the domestic tranquility". In others, to support the State or the Government--and the two are not the same.
While a Swiss or German might be outraged and glare at you for jaywalking, in a major US metropolis you might be pushed oout of the way for blocking an intersection--regardless of the streetlight and the law.
Even among our military, there have been different oaths requiring different allegainces. According to the US Army at Oaths of Enlistment and Oaths of Office
aboard Enterprise today, the top line of the officer's oath states ""I, _____, do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic;" and without going into the lesser obligations given after that, it is worth pointing out that those men
are obligated first and foremost to a piece of paper--neither the Government
nor the State nor their own military force!
It is an interesting page, and worth noting that going back to revolutionary days--the oaths and obligations were very different. But then again, as many folks both from the US and from other nations are not aware, this is the second
"United States", the first nation was literally shut down and replaced with a new one. Peaceably, by folks who were concerned with larger issues than "the law".
Legalities? That's a topic for a whole other time and place. The differences in those attittudes and obligations are something that only world travel can impress someone with. Drugs?
Well, as I said, what you do with them personally might best be considered in light of reality--which goes beyond and often contradicts "law". Who you do it in front of, is all part of that equation. The sea gods don't tolerate many fools for very long, whether they're bulldozing aircraft (aka 'reallocating material storage
priorities') or carrying a pocket full of pills.
Bottom line, is to make an informed choice about what you're going to do. The priorities you make it upon, will of necessity be personal ones deeply ingrained in your cultural training.
Or as my friend's wife said on seeing a Shitzu being carried in a local supermarket, "Look, Husband! Such wonderful fresh meat they have here! Please, ma'am, which way to butcher department?"
