Out actor Zachary Quinto has been juggling his acting career for the last six months with campaigning for the re-election of US President Barack Obama - an election that the 35-year-old actor considers to be the most important of his lifetime.

Quinto, best known for his role as Mr. Spock in the most recent Star Trek films, is dismayed by the Christian right who have such a big influence on the Republican platform when it comes to social issues like LGBT equality and abortion.

'It boggles my mind that there are so many extreme Christian organizations that are adopting a stance against homosexuality with such a vitriol and hatred and targeted aggression that goes against the tenets of the Christian faith,' Quinto says in the new issue of Out Magazine.

'The hatred that people are leading with in this discussion is really, for me, the biggest symptom of how sick we are,' he adds. 'It’s the thing that makes me look at our culture and think, We are so far afield of any sort of connectivity or truth in relationship to one another.'

In the Out interview, Quinto also discusses his decision to come out publicly as a gay man in an interview nearly a year ago.

'I thought about it as coming out from behind the wall,' he says. 'Walls now are only as high or as thick or as strong as we allow them to be.'

'One of the most defining conversations that I had with myself was that absolutely no good can come from me staying quiet about [my sexuality]. Literally, no good can come from it. But if I take the step to make the acknowledgment and be honest, so much good could potentially come from it.'
