Martin Luther King Jr. was not all he was cracked up to be. He was the adulterous "Bill Clinton" of his time. His name wasn't even real, he was born "Michael" and only changed it to "Martin Luther" because MLK Sr. was calling himself that. He had ties to Communism and plagiarized the work of another to get his Ph.D.
More facts are available from http://www.martinlutherking.org Celebrating holidays for an adulterer will be beyond the pale of the United States and so leaders won't go for it, and certainly won't go for it when FBI surveillance tapes of King "relaxing" in hotel rooms become unsealed in the year 2037.
