Leviticus 19:19 and why Christians should wear poly / cotton socks and undies

A friend sent me a meme on Leviticus 19:19. The meme was confrontational and deliberately offensive. Since Christians wear polyester and cotton socks which are a blend of two materials – they break Leviticus 19:19. ‘Do not wear clothing woven of two kinds of material.’ So, how can Christians say anything about sexual ethics or anything else that might spring from Leviticus as a standard since they break the rules themselves?
