I think he's left the thread but it seems that he left out the word
" A" ...in his sentence. I took it as him meaning "There were 22
genocides in the 20th century.
Genocide is not a problem that the Jews had,(notice the comma he used here)
it is
"A"(he missed putting the A here)
universal problem of our world today. So the answer(explanation) he is intending is immediately following the
"comma" he used in the sentence.
With the word "genocides"(plural) or "genocide"(singular) there is the luxury of the added "S" to denote plural or singular usage but with the word
holocaust it is used in a singular tense and there is no "S" added example,(
holocaust's). Holocaust means consumed by fire on an alter
or it was first used by the New York Times in 1895 to describe the massacre of Christians by the Ottoman Muslims(see terminology in article)
https://en.wikipedia.org/wiki/The_Holocaust So with the word holocaust it is used with no "S" to describe other genocides other than just
"the holocaust of the Jews"(ww2) but used this way it is always preceded by the word
"The" as in "The holocaust" but then which holocaust it is referring to is dependent on the discussion's usage.
Now as we know in the modern days there is an fascination with the term "fake news" and one of the chief sources of this is the NYTimes(quoted in the Wiki. article) and many others so it's wise to consider that "fake News" is not a new thing but has gone on the whole time. Here is an source that does the same thing(holocaust denial by trivializing facts)
https://www.britannica.com/story/what-is-the-origin-of-the-term-holocaust I'll point out it's wording and intention because it's easily missed. In the third sentence in the article it states "
and millions of others". In the article it's focus is to put a
"dot in the middle of a circle" ,,,the "Dot" is that it is speaking of the "Jews"(in the article) and so it draws the focus away from "and millions of others" by stating them as "the trivial" amount in the article.
In actual history the number of the "millions of others" is around 11 million and then 6 million Jews(the smaller number of the two) but the focus of the article is "on the Jews only" and so it is not added together(11+6=15 million) and called "
the holocaust" but instead states "killing of
six million Jewish men,women and children" by trivializing the "millions of others"(=holocaust denial by trivialization) when the fact is that 15 million
people were murdered by the Nazi's in the same exact manner.
