Roseanne basically says that Hollywood stars are terrified of using their status to speak out about important issues because there’s a “culture of fear” going on there, where “speaking out” almost automatically equals being shunned from the industry and having one’s career destroyed.

More importantly she adds:

“It’s also a big culture of Mind Control. MK ULTRA Mind Control rules in Hollywood.”

This means that many stars do not speak out because they literally cannot do so. They are mind controlled which means that they have alter personas programmed into them that handler are able to trigger and control at will.
