Planned Parenthood refused to accept the donation, as they should have. The only reason he would try to do this is to get his name in the media and cause a stir. If PP accepted the money, the right wing media would have had a hyper-conniption freak out. Since they did not accept the money, Max gets to play some kind of weird victim card and (along with the same right wing media who would have crushed PP had they accepted it) accuse PP of not wanting to accept the money to help women. For Max, he gets the publicity either way, and in this case, he didn’t have to spend a dime.
Really, this is a simple choice for Planned Parenthood. If they accept it, everyone in any political circle would have had issues with it. The left would be uncomfortable, the moderates would find it unseemly, and the right would go into full assault, poison the well mode. It’s not even an option.
I’ve never read Max’s books, but I’ve heard three or four interviews of him telling outlandish stories which demean and sexually objectify women. You can go find them on your own if you wish. Max has his fans, and even has his female fans, but he’s politically toxic. No one in politics wants to be associated with him in any way. Not even if he offers to give them $500,000. And that’s because he’s scum.
