Why does the Left hate Beauty?
Because Leftists, Marxists and Communists demand everything be made 'equally' miserable and decrepit to the lowest common denominator they can foist upon the people.
Jealousy and envy is one of the prime motivating factors of ugly individuals that assert it is unfair that anyone is wealthier, happier or prettier than they are. So everyone must be forced to be put on the same level or lower than those doing the bitching.
Of course, remember some animals are more equal than others are - so the rules put into place to keep those they want punished in their place do not apply to the rulers or their constituencies.
