Can't see another post on this but popped up today. Seems like a strange location for political graffiti, to say the least. I'm going to go ahead and assume that a stately home has very few links to trans people. A grave completely unrelated to 'the cause' seems like an odd choice of location.
Not really sure how to drop a link, so apologies if there's a tidier way.
