This is a product of taking away choices and opportunities. And, now that the Grand Boasting Session is a thing of the past (unless someone comes up with a January Kingdumb Misery insert article about one, I assume that they are finished), those days where you had between 5,000 and 8,000 people together are gone. With the field limited to 500-700, you are pretty much restricted to whatever is on hand.
This is also a big reason why you get crappy choices. Especially when you get older women stuck with younger men, that could produce the problem of not having any children (when the men are older, that is less of an issue). Or, you get a Jewish partner marrying someone that is fully Gentile, where neither are comfortable with this situation (which is about as much of a problem, if not somewhat bigger, than marrying a different race because no one of your own race is available). But worst of all is when "sisters" are stuck with abusive tyrant "husbands". You know, the sort that everything the wife does is what the husband demands she do. This is as common with marriages with no racial differences, close ages, and that "should work". Many of these "marriages(??)" are arranged by the hounders.
People should have the right to choose whether to marry across races. People should have the right to make their own decision whether to marry a Jew (or if they are Jewish, to marry a Gentile). People should have the right to choose whether they wish to marry someone much older or younger than they are themselves. These issues should never be forced on anyone because there are limited options or because the hounders feel like arranging something (which is when they are least likely to work out). And most of all, no one should ever feel forced to marry a tyrant simply because no one else is available or because Brother Hounder thinks it would be cute.
