Let me start off by saying that the Jew will always continue to push their racemixing filth everywhere they go and that the only way to get rid off this, is by getting rid of the one that continues to push this filth, irregardless of the damage it causes. tl;dr >>10731
It is a fact that the Jew and their Goyim are pushing the Interracial meme. Any pornsite you visit has 20%/30% "Wife gets plowed by black dick while man tapes" or other tripe on the front page. There's no need to explain here why this is so. It is also a fact that there's a growing portion of the Gentiles that willfully participates in the further degeneration, either by participating through masturbation or creation of IR-porn. I do not think the numbers are as high as you think they are and even if there is a substantial portion of the Aryan population that's doing this, there's only a small population of whites needed to reboot the population ( >>10733
Considering the subject, I think it's crucial in this matter to consider that there's the truth and the Jew's projection of the truth. I will like to explain this through an example: I read a book about some French General during the time of the war with the English somewhere in the 1500's. The general was outnumbered 10 to 1. The French General was situated in the hills with some plucks of forests around, while the Brits had surrounded him. The Britons only needed to attack with their vast numbers, and the French would've been annihilated, effectively ending the General's campaign. The French General thought of a ploy to fool the Britons: he ordered his troops to move around in their camps so that the Britons could see them walking around. He also ordered them to change clothes while they were out of sight, march in different formations, with different people, to carry weaponry and equipment from place A to place B, and the same weaponry from place B to place C. All this is done in the LOS of the enemy. The effect of this was that it seemed like there were 10 times more soldiers and weapons than there actually were. The Britons believed what was being displayed to them, called off the attack and left.
How does this relate to your story? The fact that 1.000's of White couples willingly participate in black cuckoldry, is by no means proof that millions of Whites are doing this. Remember that the Jew hosts all the Porn, (Social) Media and is very active online (IT is the biggest business in Israel). The Jew can possibly create an illusion where you could believe this (i.e. Have ca. 500 couples on rotation, create more sock puppet accounts for either creation or commenting.. etc basic population manipulation). I think it's also important to consider who's participating in this and if they are truly part of the Aryan Race (i.e. are these couples White or (((White))) ). Jewish Subversion is already done everywhere else, so you can also expect it in the bedroom.
Still, it's on the rise: agreeable white countries such as Canada and Sweden are quickly collapsing under their progressive leadership. In big cities in Canada, an interracial relationship is "the thing to be in" and this has been achieved through a coordinated effort by the Media, Schools, Politics and Social Influencing. Consider SI, The Jew uses role models to further this agenda: by using pretty, attractive, white celebrty women (Georgia Ellenwood from Canada, or Doutzen Kroes from the Netherlands) they actively influence young, naieve, impressionable white girls to mix. Again, the only solution here is to remove the ones that have created or are keeping this in place.
Considering names like "Stags", "Vixens", "Snowbunnies" or whatever other name the Jew has conjured up: I know it's real. Whites who fall for the "Whites are evil" meme also have low self-esteem. Whites who Racemix have low self-esteem. People who participate in porn already have low self-esteem. Whites who participate in IR cuckold porn are at the bottom of the self-esteem barrel (with all the white guilt + feminism tripe they believe). Getting a 'cool' name like 'Vixen' or 'Stag' is something that works really well for these people and not something that you should get so rustled over.
