Nope. being afk is rude as it forces people to wait the entire vote time, and it prevents crewmates from finishing their tasks. Or if you are impostor it makes it harder for imps to win. If you go afk you should fully expect to be vote kicked when you return.
If someone was afk and you had a three minute vote time, wouldn't you vote kick them as well? If so then you are just as much of a hypocrite as you claim others to be. You are not a hypocrite if you vote people out for being afk, as long as you don't complain when people do the same to you
