Earlier quoted context omitted.
"washing" is a euphemism for pressing a button, though
No, for many people "washing" is a euphemism for gathering clothing from various rooms, sorting it into different loads (hot wash, cool wash, whites and colours), loading the machine with clothing, loading detergent (and buying the detergent), pressing the button (while selecting a program that doesn't destroy the clothing), taking the clothing out of the machine and putting it in the dryer or hanging it on the cloth…
You buy detergent when you buy toilet paper, you throw your cloths into a hamper to not have to run around to gather them, and you hang them on a line in max 10 minutes. Ironing is something you don't need to do unless you want to buy cloths that require it.
Just because something might be done primarily by women it's not sexist to call it easy.
