John Macarthur and other Pastors stuck in the Past?

I find it interesting how John Macarthur claims there was a "revival" in the 1970s. I read that John says in the 1970s people were being mass baptised in the Pacific Ocean, turning back to Jesus. Billy Graham was real big too. Also, John Macarthur often has used AIDS as an example. Interesting thing is that in the 1970s AIDS was this big mystery disease causing hysteria. So it would have been a good example back in the 1970s and 1980s to really capitalize on peoples' fears. Personally I feel that America slipped from its great revival around the Civil War Era. Before the Civil War around the 1830s to after the civil war to the 1880s seems to be the time when a lot of kooky cults and higher critics reared their ugly heads. I don't see any generation after the 1830s, especially after the 1880s as having been highly moral and God fearing. In fact I find many people who are 70+ years old to be very immoral. I see people who are 70+ as having been some of the first failures of Christianity. I think the 1900s was the century of nominal christianity. It only took a few World Wars to really capitalize on the hypocrisy of Christianity in the 1900s. Now back to John Macarthur; don't you think it's a bit weird how John and other pastors are historically myopic? Pastor Hal Lindsey, a great christian man too, has a thing for claiming the 1950s was a great Christian Era. I notice Hal Lindseys' hay day was in the 1950s; just like John Macarthurs' hay day was in the 1970s. This is a bit trivial I admit, I just wanted to express this as something I find irritating because of the dishonesty. In John Macarthurs updated NASB study bible he's still using AIDS as an exmple. It's not the 1970s, were all aware of what AIDS is and it's not a big scary unknown as it was in the 1970s.
