Let's do some simple historical material analysis to find the correct answer.
Marx and Marx*? Epic stache bros (and beards to go along with it)
Lenin? You guessed it, a great mustache.
Stalin? By God, look at that glorious stache.
Krushev? No stache!
Gorbachev? Stacheless.
Mao? Where is the hair?!
To further prove the rule:
Castro? You guessed it, stached and bearded.
Ho-Chi? Rockin a nice stache.
Edit: Marx and Engels*
It's not the
beardstache on the outside that counts, it's thebeardstache on the inside
To grow ostentatious facial hair, that's not liberalism I guess but it's a hassle and kinda burgeois decadence if you squint really hard
Mao had the means and ability but chose not to out of respect for the mass line.
Mao had a sweet haircut, which has to count for something.
Khrushchev on the other hand... what is this non-hair revisionism?!
