Although I would not be capable of believing in evolution anyway, and I am not capable of being a materialist, it doesn't have much to do with my belief in Jesus specifically, although that solidifies my lack of pure materialism
Because while you are an anarchist now. Without a strong materialist basic, you risk to create a "stargate" toward less beneficial beliefs system on the far right.
I will take the example of those two women:

Who, in the past, fought with the femen. A feminist movement of the liberation of women. You could have categorize them in the left.
BUT
Their fight lacked a lot of sociological and materialistic basis, render their struggle individualist. Their radicalization was not based on knowledge but anger and so.. in the glimps of a few years, they radicalized to the far right and are now defending racist theories such as the great replacement and transphobic rethorics and people.
So be careful of that. Because those are stargates between the left and the far right that can be without return.
So no...it isn't "impossible" for someone to radically change their opinions in a short period of time, just unlikely and it probably won't be a change due to deep understanding but appealing to authority or emotions
