Snowman Goes PC. Becomes Snowperson
The mailman is now the mail carrier. The waitress is now the server. The stewardess is now the flight attendant. The foreman is now the fire fighter. The chairman is now the chair person. (Feel free to add more in Comments.)
So it is without surprise, the snowman has become the snowperson. At least in Winsper Inc.'s Christmas card, Winsper Wonderland, where you can dress the snowperson any way you want and send it to a friend without fear of offending their politically correct sensibilities.
