The so-called Christian leader who keeps spouting that natural disasters are a response to gay marriage or sent by God to punish homosexuals is saying that they're because of the sins of those people. I'm not taking pleasure in the loss of his house, but since he opened up the discussion, asking him about his sins should be fair game.
While two wrongs don't always make a right, this is one case where pointing out the hypocrasy of someone else is not unfounded. After all if natural disasters are being caused by homosexuals, either the person is wrong, or they themselves are commiting some kind of immoral act and need to change their ways.
No, I believe it makes not sense for a reporter to ask this type of question. Furthermore, it is ridiculous for someone to blame a natural disaster on homosexuals. I think one absurd statement should not justify an equally absurd question. In other words, two wrongs don't make a right.
There are some devote believers who truly feel that natural disasters are a result of nations turning away from religious faith and society, in their opinion, becoming increasingly sinful and tolerant of sin. These individuals are in the minority and not taken seriously by most. They should not get additional attention just so a reporter can stick it to them in a disaster.
