Washington, April 15 : South Africa-born Charlize Theron thinks US ban on gay marriage is another "form of apartheid".

The Oscar-winning actress revealed that she was "bothered" that her adopted country failed to legalise same-sex unions.

Charlize said it was this "caveman" approach which reminded her of her native country''s past apartheid laws, which marked a distinctive line between whites and non-whites.

"I don''t like living in an elitist world, it bothers me. I don''t want to be part of an elitist sexual preference," Contactmusic quoted her as saying.

"It bothers me, maybe it''s because I come from a country where I lived under apartheid but this is a form of apartheid and I don''t want to be a part of that.

"My ability to get married is a piece of me that I wish I could give to somebody who it would mean so much to. We should all have the chance. It''s just so caveman, I can''t believe we''re still talking about it," she added. (ANI)
