MCD can mean a lot of things.... But, that is in the eyes of the buyer. I can think MCD as Metals, commodities, and domains. In short, you don't need to set the tone... You end up narrowing your focus when such a narrative is set in stone.
But this statement of yours could simply be registered as a proof that you've "registered" this domain "in bad faith", should the fries owner seek damages citing you are infringing their rights. This is a statement that might be openly challenging them to a trade war, If the domain owner wants to build a business competing with McDonalds, they can sell this domain to starbucks for free lattes.
