I'm quite fascinated with those people's use of the word "cucked" which is in the OP. I assume it means cuckold, unless it gained some other meaning in the alt-right circles.
But why is everyone who disagrees with them is a cuckold? What is with them and cuckolds? Are these people responsible for why I've been seeing a lot of cuckold-focused porn popping up online lately?!
Cuckolds are "weak." A lot of cuckold-based porn involves racism, in that a "black bull" has sex with the "weak white man's" wife, and in that sense turns the black man involved in the porn scenario into an 'animal' defiling the woman, almost equating it to bestiality in the consumer's eyes.
The general power dynamic is that either an oblivious, schlubby weak white guy is unaware that his wife is being 'ravaged,' or that he somehow gets off on it.
In essence, calling someone a 'cuck' is essentially saying they are weak and cannot properly satisfy their wife.
To add to this, you can transpose this power dynamic into racial politics and international politics as well -
Politicians can be "cucks" by being too weak to 'stand up' to Trump and ending up serving them, like Ted Cruz. They can also be 'cucks' by "rolling over and letting immigrants flood into this country and have sex with OUR white women." It can even be something like "Our president is a cuck, letting foreigners ravage our country and standing by letting it happen."
Do you get where this is going?
