HERE'S A DIFFERENT KIND OF REALITY IN THE U.S.A. THAT PEOPLE TURN A BLIND EYE TO BUT AFFECTS THEM DAILY AND WILL EVENTUALLY KILL SOCIETY AS YOU & I BOTH KNOW IT UNLESS WE STAND UP & STOP THEM!
===========================================

***PART 1

THE U.S. CITIZENS HAVE THEIR BRAINS SCRAMBLED VIA FLUORIDE IN THE WATER & ALL THE ASPERTAME THEY CONSUME IN POP DRINKS, BUT THERE IS MORE.....

You see, Bush Sr., & Jr., Clinton, Reagan, Carter, Obama, Ford...ALL these presidents are in what is dubbed a SECRET SOCIETY called The Moloch Axis Demoniacs (i coined the phrase myself...Dr. A.P. and i don't use my full name because WHO knows WHAT sinister crap they'd do to me IF they found out?) or M.A.D. for short.

These people, and there’s obviously more of them (Cheney, Rumsfeld etc.) than the ones mentioned, control KEY positions not just in government, business, finance, society etc. They not only perpetuate what will keep them in power today, but take steps to GRADUALLY erode MORAL, SOCIAL and FAMILY VALUES in society. This degradation is so gradual that it's like hair loss! You see it ever so slowly and you have to be a keen eye to boot!

For example, women in the workforce...they go to work so WHO takes care of the kids? Some goofs getting minimum wage who could care less about those kids. Family split apart because NOW both parents work and the cost of life itself purposely increased to perpetuate this separation. Kids grow up with NO moral/social/family values. Repeat this a few generations and before you know it, you have mindless zombies that don't know RIGHT from WRONG! The masses will be easily programmable to get in debt, and be anti-Christ-like etc. Add ASPERTAME, Fluoride in tap water, MSG and genetically modified foodstuffs to the mix and the process expands both rapidly & exponentially.

Also, the coming mark of the beast 666. Remember HOW it all used to be ca$h only? Then they introduced checks, then credit cards to get yourself in serious financial troubles, then ATM cards, and now that STUPID SWIPE-PASS card. What is the purpose of all this? To get people broken down enough and stupid enough through putting FLUORIDE in the drinking water and ASPERTAME in soda drinks/pop cans so we ALL can accept the 666 chip. So NOBODY can buy or sell or own ANYTHING lest he has the mark of the beast (anti-Christ) which is 666.

I can go on for days & days as to the subtleties and more examples but i think you all SEE the points i make here. It's all SUBTLE and GRADUAL negative changes day in & day out that these M.A.D. demons (because they are demonic and have placed their trust in demons in exchange for their souls and material possessions here on earth) are passing into laws in Canada, USA, UK, SPAIN, FRANCE etc.
