The way he has worded it is that the building is “used”, etc., or is “associated with” them. He's made it broad enough so that if someone goes after any of these identifiable groups he has listed, based on their religion, race, colour, national or ethnic origin, gender identity, or sexual orientation, and who are using the building, and if the facts pan out, that person has committed a hate crime. I think he was just making the definition of the building, the structure, clear enough so it would capture anything that goes against those groups.
