Before you use this as an excuse to accuse the commenter you disagree with as being a Wumao, note that China's propaganda strategy serves to distract rather than directly engage, as they would rather minimize engagement. It's the same principle of "don't feed the trolls." Here's a Harvard paper that covers this topic more in depth, though it's about domestic propaganda: https://gking.harvard.edu/files/gking/files/50c…
> a Wumao For reference, the initial W doesn't represent a sound, so this would be "an wumao". (Same for Wuhan.)
> The form an is used before words starting with a vowel sound, regardless of whether the word begins with a vowel letter. This avoids the glottal stop (momentary silent pause) that would otherwise be required between a and a following vowel sound. Where the next word begins with a consonant sound, a is used. Examples: a box; an apple; an SSO (pronounced "es-es-oh"); an MP3 (pronounced "em-pee-three"); a HEPA filter (here, HEPA is an acronym, a series of letters pronounced as a word rather than as individual letters); an hour (the h is silent); a one-armed bandit (pronounced "won..."); an heir (pronounced "air"); an herb in American English (where the h is silent), but a herb in British English; "a unionized worker" but "an ionized particle".

For example, "womb" starts with the same sound as "wumao", but we say "a womb" instead of "an womb". For the same reason, we say "a wumao" instead of "an wumao".
