Why is there a stigma about being cautious about introducing GMOs the the ecosystem if we don't have an untouched backup of the ecosystem that sustains us. It's not as if we can un-introduce GMOs to the ecosystem once they are there so what is the problem with having strict controls over their deployment?
Because, if it was reasonable, the same caution would be applied to all new cultivars. Because we have tested quite a lot of them for quite a long time, and they don't seem to yield catastrophic results, yet it doesn't seem to change anybodies minds. Because people oppose golden rice, where most of the concerns people claim are their reason to oppose GMO does not apply. Because many of the groups opposing GMO are misrepresenting reasearch in order to make GMO seem more dangerous.
In short, because people opposing GMO does not act as they would if they had reasonable cautions about the ecosystem. In stead, they act as if they are dogmatically opposing a new technology for no other reason then it being new. That tends to draw a stigma.
FTL travel, or even FTL communication, is forbidden by the laws of physics.
It's not strictly forbidden. However, FTL communication is equivalent to time travel in special relativity. This means that it breaks causality. Since we haven't observed any breaks in causality, and special relativity is an extremely well tested theory, we assume that FTL communication can not exist.

Why? How does this help with security?
[Cannabis] is hypocritical that some far worse drugs have social acceptance such as caffeine, nicotine, and alcohol[...]
I will give you alcohol (because of we have to consume to get an effect, and that is really unhealthy) and nicotine (because of the delivery mechanism. Cannabis typically has the same delivery mechanism, but you would typically smoke less material per day, so it is not as bad), but caffeine? Really?
The graph you link to can only be used to asses the risk of immediately dropping dead as a consequence of taking the drug. As this is not the main risk for any of the three drugs you mention, it is, at best, irrelevant.
[...] as if that means anything. I know what they are trying to say,[...]
If you know what they mean, than it means something. Why are you complaining about language not living up to your arbitrary standards when it performs its purpose, to confer meaning?
