They sure want to get a lot of “false teaching organization” mileage out of one article BioLogos posted as part of a series intentionally commissioned to explore differing views on the atonement. (All having to do with the gospel, by the way, which allegedly BioLogos doesn’t talk about.) It’s right there at the top of the article "Part 2 of 7 in Atonement and Evolution: A BioLogos Conversation
Conversation is what gets promoted here, not indoctrination. I can understand that if all of your existence is wrapped up in a world dedicated to protecting boundaries and declaring people in or out of your group, then the idea of conversation about different ways of processing theological ideas would be intimidating. If you don’t have the critical thinking skills to evaluate other people’s different perspectives, then by all means, stick with groups that are only ever going to tell you what you already think and believe. I personally believe in a substitutionary atonement. But I don’t think it harms my walk with God to read an article that views God’s work through Jesus on the cross through a different lens. At the end of the day, Jesus is still glorified as Lord and humans are still in need of redemption through Christ, no matter which perspective you look at the atonement from.
In that same series, there were articles explaining other views of the atonement, like the one by Tim Keller. Tim Keller on Original Sin, Atonement, and Evolution - Article - BioLogos
It appears to me that the situation is that AIG cannot effectively deal with the evidence from science or Bible scholarship that indicates that the arguments they are promoting are not compelling. So the only tool they have left is trying to convince the people already in their tribe not to engage with compelling arguments by relying on fear-mongering and misrepresentation. They can say, “Ignore the people over at BioLogos or your soul is in peril” all they want. That doesn’t really constitute “an argument” that deserves a response, or make what they are selling more attractive to the people who haven’t already bought it.
