Oprah, producer and co-star of the new movie Selma, told People Magazine last week the protests against police brutality in Ferguson, MO and NYC lacked leadership.

"I think it's wonderful to march and to protest and it's wonderful to see all across the country, people doing it," Winfrey told People exclusively in an interview in the magazine's new issue.

But, Oprah explained, it's not enough to march:

"What I'm looking for is some kind of leadership to come out of this to say, 'This is what we want. This is what has to change, and these are the steps that we need to take to make these changes, and this is what we're willing to do to get it.' "

"I think what can be gleaned from our film," said Winfrey, "is to take note of the strategic, peaceful intention required when you want real change."

The Ferguson and NYC protests kicked in to gear, responding to Oprah.

"If @oprah doesn't see 'leadership' in Ferguson, it's cuz she's not really looking. It's grass-roots – she has to do work to see the teams," wrote one Tweeter.

"So does @Oprah expect someone to raise their hand at Protest when they ask 'who is your leader'? That messiah style of leadership is not us," Tweeted another person, adding, "Please direct @Oprah to read the posts under #YearOfResistance and #NewYearsRevolution if she is looking for leaders. We out here."

Concluded another: "The leaders in St. Louis are 'waiting on' you, @Oprah."
