Polygamy should be against the law because: (My personal
opinion)
1- In most countries where polygamy is allowed it is used by
patriarcal societies to control and exploit women for selfish
gains. Its about 'personal choice' for men but obviously and not
surprisingly no 'personal choice' for women. It is brutally and
unfairly enforced.
2- Its not affordable - unless you're living somewhere in Africa
or some similiarly primitive society - you don't want people living
on welfare with their 2,000 wives or 5,000 husbands using OUR
taxpayer money.
3- Its against human rights - obviously.
4- In most societies where it is frowned upon, it goes against
the societal perception of common decency and social values.
I personally don't give a rat's behind if they are both
consenting parties - not manipulated, forced, oppressed or
brainwashed into doing it.
If you enjoy being second/third/fourth/fifth to someone else,
dehumanised and treated like an object of selfish desire and sexual
gratification - whatever floats your boat, dude.
