The problem with secularists in general is that most tend to be leftists - when people threw out God, they had to replace him with something and most people chose to replace God with the state and worship the state.
It used to be that Christian religious groups fought over government power in Europe, until Europe decided to separate church and state. Now racial groups, minorities and special interest groups fight over government power. This is called identity politics.
What we need to do is separate church and state as well as get rid of identity politics by ensuring that everyone is treated equally under the law. That will NOT result in equal outcomes between genders and races, but they will have to live with that and understand that the resulting disparity in come that occurs in a free market is not because certain groups are stealing from other groups or because capitalists are oppressive.. it is because of differences in IQ, culture, work ethic, etc. But that requires a conversation that the world doesn't seem to be ready or willing to have at the moment.
