It true that the our secular governmental systems (europe and the USA) are at risks from many directions including the right wing christian groups.
The real secular challenge for the next 25 years is a bit different.
We are currently scoring success in many directions (same sex marriage etc) sadly in a few years time we will have to defend homosexual’s right to life, if we are faced with sharia courts.
The exact sums in the video can be debated the overall trend is correct.
We need to focus all our intellectual ability on the next secular challenge!
