Zachary Quinto has criticised the LGBT community for its "complacency" and "laziness" over HIV/AIDS.
The actor said that today's generation are "much less fearful" of the disease, which is leading to a rise in infections.
He told OUT
: "I think there’s a tremendous sense of complacency in the LGBT community. AIDS has lost the edge of horror it possessed when it swept through the world in the '80s.
"Today’s generation sees it more as something to live with and something to be much less fearful of. And that comes with a sense of, dare I say, laziness."
Last month, it was reported that HIV diagnoses in the UK reached a record high in 2013, with diagnoses among 15 to 24-year-olds having doubled in the last ten years - read more here
Meanwhile, Quinto also spoke about his decision to come out as gay in Hollywood, saying that "absolutely no good" could come from him "staying quiet" about his sexual orientation.
