Since many philosophers and professional thinkers consider themselves the smartest mind in any given room, it comes as no surprise that they would want remove morality, and more specifically God being the source of all morality. Then whatever their opinion of what is right or wrong can be promoted unencumbered and without concern for consequences that they would be accountable for. To them, there are no moral absolutes, and do not want opposing viewpoints that they cannot manipulate or control. Right and wrong gets in the way.
