The one Jackson's doing is literally the "A-ok" symbol.
Probably a lot of us are unintentionally using the A-ok symbol not realizing its true meaning. Now that I know the meaning, I avoid using this symbol.
The "I love you" symbol used in public schools is also one of these diabolical symbols used by a lot of people.
For example, the picture below taken of Obama may be an innocent "I love you" symbol," or it could have a deeper meaning recognized by those in Satanic or Illuminati circles. Thus, it is best not to use it once we recognize the double meaning of such symbols.
