Group A respected the most important rule of traditional marriage which is to forbid and punish extramarital sex and allowed men up to four wives if they could support them but prescribed monogamy as the ideal.
Group B was sexually liberated and were uninhibited in having under-aged sex and fornication was widespread and normalised. They also condoned divorce and never married mothers, indulged in sodomy, fornicated, committed incest, gave its five year old schoolchildren sex education classes to get them hooked on recreational sex nice and early as well as allowing its infertile women to use IVF and allowing its LGBT couples to "marry" and have surrogate babies. Worst of all, free online porn was available to all and Woman's Hour - which is even worse than porn in corrupting the morals of the women - was broadcast 6 days a week.
What do you think will happen to the genetic stock of the respective groups 100 years later?
Who do you think would win if the two groups were to wage war against each other?
How much longer will you retain Western hegemony if you are too stupid to work this out, pretend you don't know what I am talking about and won't discuss this with me on your alt-right YouTube channel?
