This would be a really cool shirt, right?
Well, from what I've been reading on the internet, some time ago, actually I think it might have even been the September of last year, Sir Ian McKellen, the famous british actor who played both Magneto in The X-Men and Gandalf in The Lord Of The Rings movies, appeared in this t-shirt.
However, after further searching, I found out that the logo on the shirt is actually photoshoped, and the original shirt looks like this :
Sir Ian McKellen wore this shirt for the support of the gay and lesbian community, in a demonstration against the Vatican Church and the Pope, who was at the time in London, among others protesting about a variety of things such as the funding of the visit from the British government as well as the way Vatican tackles the child abuse cases within the Catholic Church. Sir McKellen, is a frequent activist, especially concerning the support of LGBT rights and has attended in the past a great number of protests and demonstrations.
Yet still, I think the photoshoped t-shirt would look pretty awesome! :)
