What are you talking about? Clift had a heart attack. AIDS was unknown in 1966. (If you're talking about Rock Hudson, his movies are on all the time!) I'm sorry you weren't aware of this; does it really ruin his movies for you? Here are some links: (by the way, I didn't know his sister in law is Eleanor Clift!)
Here's a link to the imdb bio:

of course it ruins the movies.
Same as barbara streisands rantings have ruined he old movies. Same as George Clooney does not get my box office dollar.
Why would I want to see anything that supports the left.

Even the references you cite do not give afirmative evidence, if anything the reference to "developed a more sensible life" following his post car accident drinking would tie into the reference to the "guilt" reference in the article.
As for the wikepedia. That is way too discredited to be taken seriously on ANY subject.
