Bloodstained Men

Website for group is at https://www.bloodstainedmen.com/

From their About section:

'Bloodstained Men as an organization can trace its origin to the decision of late intactivist leader Jonathon Conte to bring seven sets of white painters overalls marked with red crotches to the protest at the October 2012 American Academy of Pediatrics convention protest in New Orleans. Though the visually arresting bloodstained crotch protest concept was a 2010 creation of British intactivist Richard Duncker, Conte’s deployment of the suit was the first example in the United States and was the spark for our organization. Seven men boldly wore these suits outside the convention hall, causing quite a sensation among the conference attendees and veteran demonstrators alike.'
