You can't go after stupid with logic.
You gotta go after it with equally, if not more outrageous levels of stupid.
If am embryo is a kid, go for child support from the date of conception.
Sue for life insurance rights/benefits.
Get voting rights lowered by a year since the time in the tummy counts as life.
Just do the most outrageous things you can possibly think of and get legal precedent set based on the new state of stupidity.
You can only fight stupid with stupid.
Go do your best stupid.
BTW, in Canada, about 20 years ago, a brilliant comedian named Rick Mercer showed us how this was done.
At the time, the right wing nut jobs led by a man named Stockwell Day tried to kill same sex marriage legislation by campaigning on citizens being able to demand referendums by gathering enough signatures on a petition.
Mercer then decided to show us exactly how this was done by getting thousands (hundreds of thousands?) of signatures to hold a referendum on Stockwell Day changing his first name to "Doris".
The campaign promise was quietly dropped during the election. He also failed to become Prime Minister (thankfully).
