A line of logic can be true even in the person making it is a jerk. And we only have this person’s word that this Ravi guy - never heard of him myself - WAS a bad person.
Don’t know anything about this Ravi, but I’m not going to assume he was evil personified just because of an article on the Internet. And....I just don’t care enough to spend hours trying to confirm things for myself.
If his logic was right, then it was right. Or not. Kind of like a medical opinion....
I saw a few of his messages on one of the many Christian stations on DirecTV. They were solid Christian messages. I have heard about the rumors and they are disappointing (basically similar to the Al Gore stories). But he did present the gospel well when I watched him.
Imagine a small town with one intersection governed by a stop light and monitored by a corrupt cop. If you are among the town's elite, and/or a buddy of the cop, you can run the red light with impunity. If you're on the cop's list, or from out of town, you're getting pulled over and getting a ticket even if you came to a complete stop at the red light.
The fact that imperfect, corrupt or simply evil people are involved does not invalidate the broader, overarching wisdom of regulating traffic at intersections.
Hypocrites who say one thing and do another should rightly be called out, but I think we all need to invest a little effort to overcome our natural inclination to focus on the hypocrite's shortcomings and failures rather than what may be the wisdom or rectitude of their words which they failed to uphold.
