The character in the middle is a representation of Guy Fawkes. In the early 1600s Guy Fawkes and a group of men tried to blow up parliament because of the government persecution against Catholics. Now, we don’t agree with his methods, but he has come to represent someone who is willing to stand up for what he believes is right, regardless of the odds against him. That, we very much agree with.
The diamond shape represents dedication. So, in turn, this patch is representing our dedication to stand up for what we believe in, no matter what the odds are against us.
