Is Ku Klux Klan an alliteration?

Answer 1

Alliteration absolutely always advances an argument, affirmatively answering alphabetically.

Seriously, it is a literary convention where by using at least three words in a row that all start with the same letter, it puts it in another's memory better. It's another way of being poetical, but it need not involve rhyme.

Hopefully helpful hints!

Ku Klux Klan is alliterative in the sense that it puts it in the memory more, but it is a name, an acronym, and it is doubtful they were seriously shooting for alliteration.
