My wife, who is the SAHM for the record, is claiming that *I* should have to clean the bathroom since my sons?

pee all over everywhere. First isn't this sexism, she is only claiming that I should have to clean it because I have a penis. Can I call the ACLU and file suit? Second since she is the SAHM isn't cleaning her responsibility? Third since she is the woman doesn't that make cleaning the bathroom, much like laundry and dishes, firmly in the realm of her responsibilities?
