Congrats, Amerikkka! You finally managed to achieve socialism! The National kind of Socialism!
EDIT: Apparently, the joke is not evident enough so I have to explain it so I'm not called a right-winger:
There is a double reference in the comment:
I wrote "Amerikkka" with 3 K for the KKK. (First part of the joke) to call them KKK members.
Then I used National Socialism (notice the capitalized words) instead of just socialism or national socialism (without capitalized words) to reference the name nazis gave themselves, to calll them nazis.
I hope this clears it up. As people are talking about "nuance" that I seem to be lacking.
