I have used similar designs in my drawings and paintings. But I am not a PEDO nor am I Muslim.
Line drawings with a focus on squares and rectangles are part of creativity exercises in art.
PEDOs and Satanists have stolen our numbers and symbols.
My feeling about instances where we find one similarity to tie something to evil, is to hold judgment until there is more evidence. It really cannot hurt to be careful, rather than hasty.
