I don't have a problem with him. He's a little more outspoken then you'd like but as I say, it takes all kinds. Some donors like to stay in the background and some are a little more vocal. So be it. You have to manage them all. I appreciate his support.
So he supports Flood, that's his right. I don't agree with it but he's entitled. You don't alienate your donors, specifically larger ones even if you may not agree with them. On this issue maybe you don't but on the next issue maybe you do. If you don't manage them and hear them out and listen to their opinions you could lose them completely. I've always said influence is a function of zeroes but it doesn't mean you alienate or disparage just because you may not always be in agreement.
Suppose he donates a few million to the athletic facility, will you like him then? As long as they're not doing anything really outlandish you have to keep everyone in the fold as much as possible otherwise opportunities to cross promote and get donations for places you can come together can be lost.
