This stamp wasn't done with offensive intentions, I respect the christian religion and I have nothing against it. The concept is: if christians can believe in a god they never saw, I can believe in unicorns too!
As a Christian, I'm kinda upset other Christians make people need to to this. To be honest I hole-heatedly, believe at one point dragons did exist, people just call them dinosaurs now. Imagination is a great thing, screw those people who think otherwise!
I believe in the unicorns xD but I also believe in God. I feel like everyone has a right to show what they believe and don't put their faith into, and if you want to not believe in God it's fine by me. We're all different after all, right? It just sucks because of all the extremists in the world of the religion. Most common today is the Muslim Brotherhood.
Just sayin', and I hate it when people shove it down others throats saying they should believe in God, etc. It's wrong! WRONG!
