Yes, some of us have. And so have you, when you rely on the undocumented and possibly self-serving statements of the van Dams, some of which fly in the face of their previous statements and/or other known facts. And I'm not talking about all the (so far) unverified stories, but going by "the record" such as it currently is.
Some people, and you can count me among them, judge a person by their truthfulness and whether or not they are forthcoming. Neither of the van Dams, thus far, has given me much reason to trust what they say, since they change it so often. And again, this is just my opinion based on the official record.
We won't get into my feelings about how much we can trust people who break their marriage vows so easily. These people remind me a lot of the Clintons, and their casual treatment of oaths and vows. That adds to my sense of distrust, too, but I wouldn't want to seem as though I'm "speculating and portraying it as fact." I do believe those rumors, however, and--please note--I have every right to do so.
I agree..there is no excuse at all for having extra-maritial affairs..
