You can't make a silk purse out of a sow's ear

Any attempt to turn something ugly into something beautiful is met with the words, "you can't make a silk purse out of a sow's ear". This is hardly fair to a sow who might claim that "beauty is in the eyes of the beholder". I have another bone to pick with " you can't make a silk purse out of a sow's ear", its discriminatory. Why not , "you can't make a silk purse out of a boar's ear"? Is it too boring? No matter, this cliche should be front and center as Congress tries to sell the merits of some of its pork barrel legislation.
