Ok, now, that could be a real problem..if..what that person takes as self-evident, isn't actually what is. And trying to explain to a lot of people, as I'm sure a lot of people that listen to this network understand, is once you start to take ideas to people that aren't in keeping what they already consider to be true...
I'm not sure if he says "...in keeping with what they..." or "in keeping what they", but it sounds like he doesn't say "with".
