If completely safe, I wouldn't mind this coming into general use for people who wish to smoke.
It's probably not completely safe for the smoker. A recent (just last month) study found that e-cigarettes do indeed contain carcinogens, in some cases showing similar levels of formaldehyde and acrolein as regular cigarettes.
Article about the study.
They used the national emergency service to inform the population about some child being kidnapped. Erh... Ok, now please tell me why I should care. Yes, yes, it's probably heart breaking for the parents, and yes, yes, if it was my child I'd certainly love to use it for that but the problem is: 99.something % of the population do not give half a fuck, let alone keep an eye out for that car. "Why the fuck should I care about some random brat I don't know about?" will probably be the reaction of nearly ALL the people who got that message.
I am skeptical that 99% of the population is as apathetic as you are, especially when it comes to the welfare of children. This is not a "think of the children" situation where the welfare of children is used to leverage some other cause. This is a case where the welfare of a child is actually at stake. Of course we care. And really, no one is asking you to get out of bed and join a search party. The point is that the information is now in you head so that if you see a car matching the description you will be aware.
I see a "cry wolf" scenario waiting to happen. Some day in the future, something actually important, something that actually is meaningful to most of the population, will happen and people will simply click it away after reading "AMBER AL...", thinking "fuck, that kidnapping fad's getting worse than spam texts".
False alarms are definitely an issue with Amber alerts as often they are issued without meeting the criteria, usually when the child is abducted by a family member in a custody dispute and is not really in danger. But if you are saying that a real child abduction is not a real emergency, I hope I'm not alone in disagreeing with you.
Transgender people are born transgender. http://en.wikipedia.org/wiki/Causes_of_transsexualism#Biological-based_theories But what would I know, I'm only trans myself. Go and cisplain somewhere else you vile ignorant prick.
No offense, but being transgendered does not automatically make you an authority on the origins of transexualism ( just as being human does not in itself make one an expert on the origins of humanity. )
The degree to which transgender people are born transgender is quite an open question, and there is currently not a whole lot of strong evidence to support that claim (as reflected in the wikipedia article you linked to -- evidence of genetic contributions is scant, and differences in brain structure cannot indicate innateness). Most likely transgenderism involves a complex interaction of genetic, epigenetic, hormonal, developmental, psychological and social factors.
In some sense I understand why transexual people and gay people (the majority of whom in my experience seem to be committed to the idea that sexual orientation is innate) want this to be the case -- we have good societal analogies for a class of people who are innately different gaining equal status. But in the long run the case for equal rights and humane treatment should probably separate itself from this question, which is purely scientific and far from settled. If the case for equal rights is built upon such an assumption, it may fall like a house of cards as science progresses, and the fact is that we should treat people humanely regardless of the origins of their condition.
