That the thing though, the interpretation of law is absolutely vulnerable to the mood of the moment.
No, not in the way the mob mentality driving criticism of this policy is vulnerable. You can try all you like, but you cannot show that angry passengers are going to make wiser, more balanced decisions. They don't. They make selfish decisions.
As a woman I am eternally grateful for it too because the mood of the Suffrage Movement bought me my right to vote and the breeze of the Civial Rights Movement brought others their rights.
Not even close to analogous. Suffrage took decades of slow change. Not the few weeks since this policy went into effect. The critics are demanding immediate gratification (because they're selfish - see above).
Beyond that, you're assuming that your personal preference would prevail more generally given the kind of depth of consideration that suffrage received before the laws were changed. I suspect that the more people think about this issue, the more your perspective fails. Indeed, that's why the critics are employing propaganistic tactics, fostering unreasonable fear, uncertainty and doubt - because they know that if people really thought it through completely, factoring in all the objectives and obligations of the government and the agency, then the critics' perspective would only be supported by a very few people.
It's not anarchy, this is the design of our government.
No it isn't. Stop making things up. Our government has a process for citizens to petition the government for redress of grievances. Trafficking in deliberately manipulated photos and engaging in FUD is not part of the design.
We have a few options to influence our governance (for what you term self serving reasons), and it's not an accident those stop gaps are present. Those stopgaps are present to prevent a repeat of the wild disconnect between the government and the governed which lead to the creation of this country in the first place.
And only a small percentage of what the critics are engaging in with regard to this issue has anything to do with that.
Again, the problem is the FUD - the inane attempts by the critics to prevail by unethical means, many of which have already been discussed in this thread, several times.
