>We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.
Notice that it doesn't say all Americans are created equal or free, but all people. Iran has no right to trample on inalienable rights.
Granted, but it doesn't necessarily follow that we have the right to trample on Iran to protect such rights. In fact, that reasoning would seem a bit contradictory.
Mind. Blown.
And I am not an America, so this is not a nationalism issue.
You could argue that based on the above, the US shouldn't have a minimum age limit for alcohol since it clearly infringes on teenagers (heck even college kids) pursuit of happiness.
I'm not arguing that it's correct that they have strict laws about pornography, nor would I argue that it's incorrect that the US has strict laws on alcohol. It's up to each country where to set its own laws.
It's only legitimate to stop people drinking when there's some danger involved, e.g. drinking with driving. One can argue for other cases like drinking heavily with a "mean drunk" personality type, or drinking heavily without the experience/knowledge to be safe in that situation. Drinking with being aged 20 isn't inherently dangerous. And it's a bad (both inaccurate and ageist) proxy for the other things that actually matter.
