Melissa Joan Hart, who stars in the faith-based film "God's Not Dead 2", has spoken on the importance of religious liberty in America.

The actress believes that Christians deserve tolerance from people of other religions, but also it's not a one-way street.

"There shouldn't be any one religion represented in anything. But at the same time, we need to be tolerant of all religions," Hart told ABC's Paula Faris of "Good Morning America."

"If a Christian's right is subordinate to all other rights, then it's not a right at all," she added. "And so, you know, I think it's really about tolerance across the board for everyone."

Hart said that her role as Christian teacher Grace Wesley, who was being persecuted in the movie for answering questions about God in the classroom, was very "challenging."

"In this case, she's an introvert... a woman who stands by her faith," Hart said of her character. "She wasn't raised with a faith and so she comes to her own beliefs and grows her own faith and then she has to stand by that conviction and kind of unwavering."

Faris then asked Hart if there were ever times she felt that she could never really "win" with the public, because her roles are always getting complaints. Hart answered yes.

"Well, before, I was getting grief before for being a witch by the Christian community," she said. "I was being persecuted for believing in witchcraft [for playing title character in 'Sabrina the Teenage Witch']. But it was really about magic and it was silly and family friendly. But, yeah, now it's from the other way."

"God's Not Dead 2," which was directed by Harold Cronk, is out now in theatres.
