the story is true.
except for one little detail religious people will ignore:

their parents made the signs not god.

even the russians themselves know the solution.

in german media, the FMBA of RIA Novosti is quoting Ludmila Luss (a scientist) who quickly found the likely cause of the childs TORTURE:

the most likely cause is mechanic or chemical interference.

i.e. with salt and pepper one can irritate the skin for a couple days.

and when you look at how ugly the signs were drawn you can be sure it was not allah, cause allah certainly, just like the christian god, does NOT exist.

and no matter how much pepper you apply to your children, you can't change that!

sapere aude you poor mislead lost souls.
