You seem to copy and paste this fake fact about 'King Henry's Little Black Book"' all over the thread.
> Blacklist comes from King Henry's "Little Black Book" which was a list of his political enemies.
While the term Blacklist does not originate from colonialism, it seems to have first been used in the 1639 tragedy "The Unnatural Combat" by Philip Massinger.
Not only did I not find any evidences supporting your fun "fact" about "King Henry and his enemies", the name Henry was quite popular as far as kings go, but non of them even lived in the 17th century according to this list: https://en.wikipedia.org/wiki/List_of_rulers_named_Henry
Back to the term - while blacklist _origin_ has nothing to do with racism, it's counterpart, "white list" was first used in the mid 19th century (not sure where it was first used exactly) - while the people who made these terms popular in the 20th century perhaps were not racist, they also were also did not think about how black people would feel about labeling white with "allow" and black with "reject", and I while I can't hold it against them since it might have been different times, the fact that some people are trying so hard to keep using these words, despite being triggering toward some people is hard for me to understand without making cynical assumptions about their motives.
Attempts to make it a racial thing are ahistorical and racist in and of themselves.
