Everyone has a "worldview", regardless of whether they've ever had any religious indocrination or not.
Worldviews are always religiously held. Though evolutionary atheists like to believe that it is by “reason” that they adhere to the presuppositions, ideations, theories, etc. of which their worldview consists, like all believers, they hold to them religiously. Most in fact, are as zealous in their beliefs as are the most zealous of Muslims. Meaning their desire to enforce their beliefs, i.e., evolution, ranks with Muslim enforcers of Sharia. This is why evolutionary atheists murdered in excess of 160,000,000 during the 20th century.
