I'm just interested. What would be an example of it being skewed to the Left?

Rhetorically speaking, of course.

Efforts of social change.

Mainline Protestant Churches and the Catholic Church (outside of their stance against abortion/contraception and that lunatic Donahue of the Catholic League). Liberation theology, etc.....

That's funny! Two liberals expressing the need for religion to become more involved in politics, society, subjective morality and advocate for their own twisted views rather than the views of the faith and objective morality. The inanities at Clipmarks never cease to amaze.

Actually, Debbyski, that is pretty much the lot of what Churches do, strive for social (community, world) and personal change. Perhaps you just don't care much for the efforts.

Perhaps you just don't care much for the efforts.

No, actually I applaud those efforts. That was the point of the clip.
