Rational: In Hebrew, “arranged” would be “mesudar”, which suggests organized. The word shidduch applies just as much to a professional matchmaker involving people who hardly know each other (common only among the self-perceived aristocratic types), to friends and relations that make a shidduch (roughly a very heavy blind date, since the preliminary exchange of information that take up the first few dates for goyim are done before hand), to the phrase that “HaShem made the shidduch” which would suggest a random event but Jews hold that nothing that happens in this world is ever random or by coincidence.
Among the goyim, arranged marriages usually involved children who were requried to marry for political, economic and dynastic reasons and the children involved were expect to be compliant (and in many if not most cases, the managed to fall in love and live happy lives until one of them died of something like a mild infection or childbirth as was common back them). If you learned humash Berishis and remeber Rivka Imeinu, you would know that “arranged marriages” without the parties consent are not allowed,
