Didn't Energy Adventure open AFTER she came out? And I know Steven Tylers drug and alcohol abuse was public BEFORE RNRC opened.
Besides, Drug and alcohol abuse are not really taboo anymore and do really think Disney is going to pick a side on anything Gay? They either tick off a huge portion of their fanbase and employees if they come out anti-gay rights or they tick off a huge portion of their fanbase and have the baptists protesting again if they come out in favor. They play Switzerland, smartly, on this issue and so while people grumble, no gets too upset. Ellen is a none issue.
It is interesting though that Jacko still retains a lot of his former celebrity, while OJ, who also was not convicted, was a pariah. Its funny how the public views things like that.
