IndieGoGo Life may be an alternative. Their terms don't prohibit abortion specifically.

The petition link didn't work for me, but I was able to search and find it on NARAL's page.

and to be clear, in case anyone thinks I'm saying no to personal fundraisers, I support personal fundraisers because direct cash grants are the best form of charity.

it's just that GoFundMe's ban on funding abortions is wrong.
