Aside from that: I wonder what would happen if all the people in the country who are using marijuana at least semi-regularly were to go to some very public place at the same time and light up a joint.
I think it's pretty obvious what happens when you light up a joint in public (in the US anyway). You may not get arrested every time, but keep it up and you will.
That obviousness surely elevates their response to DH4.
Yes, it is obvious. So obvious that assuming that that's what the grand-grandparent is proposing is either disingenuous or extremely uncharitable.
Instead of a posting a glib response, a reasonable thing to do would be to read the wikipedia article on civil disobedience and realize that a single person randomly disobeying a law in public is not how it works.
Well gee, sorry I didn't refute your argument in the form of a DH6 retort in the form of refuting the central point. What most people on the internet seem to miss is an incredibly profound insight.
We are on the internet. Most of these conversations will go nowhere beyond where the people reading them will take them, which is nowhere. I am not interested in writing essay after essay debating things with people who have no power to change them in the first place. This is a waste of time. The internet primarily exists as a form of entertainment. This may be against the spirit of HN but I would argue that HN is against the spirit of the internet. My proof of this is that the vast majority (99%+) of the internet is nothing like HN.
Anyway, to address your point - numerous people take drugs publically at events like music festivals. The result of this action is a lack of arrests and a lack of policy change.
