My personal opinion is that it is more dependant on personality and culture, than it is on tactics and management. Football is generally played (and Managed) by people with a lower standard of etiquette, lower educational achievement and (anecdotally) less grace and patience. Whereas the Rugby culture, including players, managers, coaches and fans, tends to be....better.
I tar with a very wide brush I accept that, but it's just my personal experience of being on, and having children on, both Football and Rugby teams from age 4+.
In essence: frequent, reactive shouting = Football. Infrequent, proactive instructions = Rugby
