Englishman, in the US we have Freedom of Speech and of Press.
That doesn't give you the right to post pics of people who are exercising their right to worship as they choose to. In particular it doesn't give you the right to post mocking comments about them on a site that doesn't belong to you. You've been asked to stop doing this by the wife of the forum owner who was courteous enough to request this via IM. You chose to ignore her request and continued to post pics of JW's accompanied by your own personal mocking comments. Now you're being stopped from continuing in this course of action.
