Will you take 2:1 odds? I'll send $10 to a charity of your choice if Roe isn't overturned by August, if you agree to send $20 to Planned Parenthood if Roe is overturned.
That's a reasonable bet, you're on. End of August deadline, my chosen charity would be the Green Beret Foundation (having nothing to do with the issue in question; I just believe that their work does direct good for those they serve).
I've set a calendar reminder and commit to this gentleman's agreement. Will provide proof in form of anonymized donation receipt screenshot should I lose.
