It implies that the list of people you don't like think they did something wrong but refuse to feel shame about it.
To me, all those people are not shameless - in the sense that they don't feel shame _at all_ -, but don't feel shame because they don't feel like they did something wrong (how can you think you're wrong when you don't _believe_ in climate change ?).
So shame in itself is not the problem.
