Linda Harvey, a host of the Ohio based Christian group Mission America has again spoken out against equal rights for gay people, saying that churches should be more proactive in opposing it, in the same way they fought to abolish slavery.

During her daily bulletin, she said “homosexuality is ripping apart people’s lives and families”, that churches were too busy to “equip” children to oppose homosexuality, and said that people should spend more time teaching against “the destructive effects of homosexual behaviour.”

She said: “Many of us watch in dismay as younger and younger children are told that homosexuality is a right for some people. Our church youth groups are busy with paintball and trips to amusement parks but doing relatively little to equip our children to apply the word of God to this current debate.

“How corrupted do children have to get before adults will cry out and say: no more. I hear people saying, ‘well we don’t want to get into politics.’ Strangely that objection is only raised when the subject is abortion or homosexuality, yet there is nothing wrong with Christians and even churches getting involved in a political issue, people of conviction do it all the time. Hundreds of the more liberal churches are very outspoken about how to use government dollars for entitlement programs, for instance.”

She went on to draw a comparison with abolishing slavery, suggesting that Christians should be more proactive in fighting against homosexuality, even if they are deemed “extremists”.

She said: “Abolishing slavery, wasn’t that politics? Didn’t Christians like William Wilberforce rise up and fight in the political realm two centuries ago to do what was right? They were called extremists then too. But actually no, this is not only about politics. Homosexuality is ripping apart people’s lives and families.

“I can’t tell you how many sad tales I’ve heard from people who’ve seen the destructive effects of homosexual behaviour in the life of a son, a daughter, a brother or a sister. The first battleground of ideas is one’s own mind. We need to equip our kids to stand firm in their convictions and know how to defend them.”

She previously praised countries which refuse to decriminalise homosexuality and said that the “radical” effort of the White House to achieve equal human rights was a “humanitarian disgrace”.

The Christian radio host in December said that same-sex marriage encourages children to have gay sex and that gay people aren’t human and should therefore not be protected under the US constitution. She also claimed that Jesus could be forced to marry another man if he was resurrected.
