Atheism+ was atheism with progressive politics, but suddenly some people thought Islam was worse than christianity, and also thought it would court conservative christians a lot better if they were more friendly to conservatism, and also also communism bad therefore we need to counterbalance that with showing that you can be both an atheist and right wing. So atheism+ fell apart, then the secularism of new atheism fell out of favor for “defending western civilization from islamism”, as far-right christians were better at big tentism.
