Bias can be detected by what the media report and choose not to report. When it comes to Pope Francis, bias by omission is the most common ideological practice.

In May, the pope met with an alleged Chilean victim of priestly sexual abuse, Juan Carlos Cruz; he is a homosexual. According to Cruz, the pope said to him, “It doesn’t matter [whether you are a homosexual]. God made you like this. God loves you like this.” The Vatican refused to comment on whether this was an accurate account.

Subsequently, the pope met with the Italian Bishops’ Conference. When the subject of gays in the seminary came up, the pope allegedly said, “If in doubt, better not to let them enter.” Thus was he affirming what Pope Benedict XVI said in 2005: men who have “deeply rooted homosexual tendencies” should not be admitted to the seminary. The Vatican refused to comment on whether this was an accurate account.

Why the disparity? Ideology. The big media are pro-gay and will report on any story attributed to the pope that fits with their ideology. They will not report on stories that do not. It’s really that simple. And that dishonest.
