What is wrong with the meme itself? Are Brits not marching against knives?
I admit the statement under the meme is hyperbole but the meme is spot on. Your own link says people can't carry certain knives and repeat offenders will be imprisoned.
I am wondering if you are just confused about the ideas of fair use, public domain, and open access OR if you are just butthurt because you didn't think of it first?
