They need to think about taking these people and placing them deep in a glacier or something, then maybe you have a chance of lasting for a while.
You really think there are going to be glaciers around in the distant future?
Personally, I don't get it; so long as you don't make me marry a person of the same gender against my will, why do I care what you do?
Personally, I don't get it; so long as you don't make me watch the Star Wars remakes with revised "shoots first" order, and bonus lumbering beasts, why do I care if other people do?
For many people out there, probably the ones who have the strongest views on "what marraige should be", there's a fear of change and a reluctance to embrace new ideas. Sure, some of these people may not even disagree with the ideas that strongly (though some definitely will), but if nothing else may embrace the "if it ain't broke, don't fix it" mindset. I know plenty of Star Wars geeks who to this day will get upset when you mention the changes made in the 90's re-releases, even though they have no effect on their lives other than changing something which was important to them.
The biggest difference, of course, is that both versions of Star Wars can co-exist, whereas with "redefinitions" of marraige, it's an either-or situation. If anything this will cement the opposition even further.
It's OK for different people to have different viewpoints - there's no empirical "right" or "wrong" on this issue.
As for the rest of your points though, I'd have to say I agree... someone who secretly enjoys the original Star Wars series but will only speak out against the re-releases when they think nobody will know they're doing it clearly is either afraid to embrace their opinion publicly (for whatever reason - it's not my place to decide why someone did something), or didn't hold the position that strongly to begin with.
"Why don't we give this vaccine to ten creeps on death row, throw them a few hookers and see what happens". We would have the answer so much quicker and in the end, if the vaccine turns out to be effective, we'll save so many more (important - yes, I said it) lives.
The experiments were designed to determine whether the brains of the genetically altered mice could efficiently process sensory information from the new photoreceptors in their eyes. Among mammals, this more complex type of color vision has only been observed in primates, and therefore the brains of mice did not need to evolve to make these discriminations.
"The new abilities of the genetically engineered mice indicate that the mammalian brain possesses a flexibility that permits a nearly instantaneous upgrade in the complexity of color vision, say the study's senior authors, Gerald Jacobs and Jeremy Nathans.
