Arranged marriages, like work, often involve driving external factors that don't amount to 'coercion'. Forced marriages, like slavery, always involve coercion. (The definition of coercion is the border dispute here). Do you concur? Or is there a continuum of marriage where "It sure would be nice to have grandkids someday" is only a matter of degree different from "If you refuse you will be stoned to death" or even "You have married this person."
