The actress struggles to understand parents who reject their LGBT children.

Sally Field says she is horrified by parents who disapprove of their gay children, claiming she actively encouraged her son be open about his sexuality.

The actress appealed to parents to accept and support their LGBT children, as she gave some strong advice during a recent radio interview.

“First of all, don’t be frightened,” she said during the chat on SiriusXM.

“And don’t put your own prejudices or fears about sexuality — your own fears about sexuality – on your children.

“Sexuality is a human, glorious part of existence.”

Field went on to explain that her son initially found it difficult to come to terms with his identity as a gay man – something she tried her best to help him do – before sharing her dismay at parents who refuse to do the same.

“What horrifies me is that there are parents who so disapprove, who are so brainwashed to think that this is something out of the Bible or ungodly or against nature,” she continued.

“It’s not against nature if nature has actually done this. Sam was always Sam, this wonderful human that he is, from the time he was born.

“Some people actually shut their children out of the house when they’re young, they’re teenagers – they’re having a hard enough time to be teenagers and own any part of sexuality. I’m still trying to figure it out!”

During the interview, she also labelled US Presidential hopeful Donald Trump as “overrated”.

In 2014, the Oscar-winning actress – who has two straight sons and one gay son – wrote a letter in support of the Human Rights Campaign, in which she said raising a gay son was one of the greatest privileges of her life.
