The blogger is entitled to his opinion of the experience, but Loretta Swit's behavior at an appearance that was non-DS related is off topic for these boards. But since her name has come up in the discussion of actors who charge for autographs, I'll add that I think her well-known history of donating the proceeds raised from signing MASH items to animal rights activities sets her apart from actors who seek only personal profit.
BTW, a post in the topic was edited per the Forum Guidelines, specifically #7, that refers to the posting of gossip and libel. The poster is welcome to send me a PM if there are any questions about it.
