Can someone please refute any of this? I'd really REALLY appreciate it

I DECIDED TO LEAVE THIS POST UP FROM THURSDAY BECAUSE THERE'S SOME INTERESTING COMMENTING GOING ON....I'D LOVE ANYBODY TO RESPOND TO NET OBSERVER'S LAST COMMENT....THANKS!

John Drew, Ph.D. is a former Marxist-Leninist who met Barack Obama when he was a sophomore at Occidental College in California.  He gave an interview to Andrea Lafferty, who wrote a long article which includes this:

As more and more information is uncovered about Obama’s childhood and his path into politics and power, it is evident that he was mentored and helped along the way by Islamists and by hard-core Marxists.
His own mother, Stanley Ann Dunham, had embraced Marxist ideology as a high school student in Washington state. She had been taught by Marxist teachers and was a proud atheist.
In Hawaii, he lived with his grandfather and grandmother while his mother stayed in Indonesia doing anthropological work. His grandfather introduced teenage Obama to Frank Marshall Davis, a black Communist, as a mentor. Davis had come out of the radical black Marxist movement in Chicago, which began flourishing during the 1930s.

According to John Drew, Ph.D., the Marxist-Leninists he attended school with at Occidental all either went into college professorships or became community organizers. Drew became a college professor; Obama became a community organizer and later a college professor.
Obama’s entrance into Harvard Law School was aided by two radical Marxist-Black Muslims. One of these men was Khalid al-Mansour, who has served as an advisor to a Saudi billionaire. (Mansour’s real name is Don Warden.) Al-Mansour was a mentor of Black Panther Party members Huey Newton and Bobby Seale, both criminals.
The other man who helped Obama get into Harvard was Percy Sutton, who was a lawyer for Black Muslim Malcolm X.
Obama’s spiritual advisor for 20 years was Pastor Jeremiah Wright, a Black Liberation theology advocate. Black Liberation theology is based on the Marxist ideology proposed by black racist Professor James Cone.
Obama’s political career was launched in Chicago with the help of Alice Palmer, a state senator who was also known to be a hard-core Communist.

Obama’s campaign for the U.S. Senate was started in the home of Bill Ayers and Bernardine Dohrn, both violent founders of the Weather Underground. Ayers had been involved in bombing a New York City police department, Capitol Building and the Pentagon in the 1970s.
In summary, from the very beginning of his life, Barack Obama has been imbued with Marxist thinking – from his mother, Frank Marshall Davis, his college professor at Occidental, and his Pastor Jeremiah Wright.

Z:  I'm hoping someone can refute any of the above...I'd feel a whole lot better  if someone can.  But, I've read stories about each of these situations above and it really gives me pause.  When I say "What do we expect Barack Obama to be like?", this is what I mean.  How could he not be very different than the typical American president who loves this country, respects it, believes in Capitalism, etc etc.........??
