Language also evolved differently in different regions and culture groups. Here in Louisiana we have much more French terms in average usage than other regions on the US. That doesn't mean that us using those term like "Laissez les bons temps rouler" is wrong at all ( and I do support voice removal of people that disagree) you can't control language because it develops to fill what it is needed for. In some regions conscience speech in important, in others more descriptive language is needed.
