Oh, rubbish. I've known men who were far less intelligent and reasoned than any woman, and they have the vote at 21. If you want to be scientific, wouldn't you find a different individual voting age for everybody? I support the current laws here in Australia, where any adult Briton over the age of 21 has the right to vote. (Well, some male Aborigines also currently have the right to vote if they voted before in colonial elections pre-1902, but that's a lesser concern as their race is on the road to extinction anyway - a hundred years from now it won't be a problem.)Most phrenologists (the understanding of which shall be much advanced in these next 100 years) already understand that the woman's head shape and brain size show they are less able to make informed decisions than men. Consequently, it will be empirically understood that a husband's guidance will be needed.
Reformists would have a dog voting in Parliament. In 2009, decisions will not be made for ROMANTIC reasons, but by scientific means. Phrenology may well determine your choice of spouse.
Oh, that reminds me - a hundred years from now I predict the Australian continent will be wholly British. By then we will have deported the Chinese and all the rest of them (like what's happened with the kanakas in Queensland), and the Aboriginal race will be dead or so diluted in British blood as to be meaningless.
