Actually, there have been rumors that Brad Pitt is gay. Also, George Clooney, Richard Gere, Leonardo DiCaprio, and just about every single other well known actor in the entertainment industry.
Type this into a Google search: " (insert actor name here) gay rumors", and you'll see what I mean. I just did it with the name Brad Pitt and got back 15,500,000 hits.
If this story had broken with the name 'Brad Pitt', or 'George Clooney', or just about any famous person's name instead of 'John Travolta', people would be writing the same things. "Oh, I'm not surprised, I've known he/ she was gay for years. Where there's smoke there's fire. I know so and so who knows so and so and know FOR A FACT that <insert celebrity name here> is gay".
Ugh. I look forward to the day when rumors are not taken as fact, just because they are often repeated. I look even more forward to the day when one's sexual orientation stops being the business of strangers.
"Where there's smoke there's fire"? ~ Not necessarily.
As a user of e-cigarettes, I can tell you that what often looks like smoke is nothing more than water vapor.
