"All of this has to be done in a very tight straitjacket."
Pretty much sums up the whole subject.
The "radicalized" Canadian was not a terrorist, he was a disturbed individual who latched onto the ideology on his own accord.
No difference. If you embrace Islam and try to kill in the name of Islam, you're an Islamic terrorist. Trying to make a distinction between a crazy person and a Muslim is doomed to failure.
A quite common preservative is sodium benzoate. Sounds pretty nasty, huh? Well, it's a natural constituent of cranberries, prunes, and apples. It also is useful against schizophrenia and urea cycle disorders.
Then there's ascorbic acid used as a preservative. It's an essential nutrient.
HFCS is widely used because U.S. cane sugar lobbyists successfully pushed for high duties on imported sugar: this allowed U.S. producers to push up the price of cane sugar. Big users of sugar in processed foods then looked for cheaper ways to get the same sweetness, and HFCS became a practical substitute. If common sugars are all made more expensive, the search for practical alternatives will intensify. Perhaps someone will find a way to make the sugar alcohols like xylitol or other chemicals tasting very much like sugar such as inositol, cheap enough.
Actually, cane sugar (or the equivalent beet sugar) is quite cheap, and the price would probably have to more than double to cut down much on most people's intake.
Any high level of taxation is stupid; the higher the stupider. High levels of taxation mean that people will act in ways that minimize the tax they pay; instead of producing or enjoying themselves, they are living their lives to avoid government burdens. High taxes of any form distort the economy. Short term, high taxes make most people worse off, long term everybody is worse off (because of the loss of technological advances.)
If the tax burden is low, it's not worth the effort to avoid it, and most people can't be bothered when they have something better to do.
