I find it strange that Descartes didn't resonate more, since I consider his position completely unassailable (since it is derived from the fact that you can know you exist ).
Same with positions that Aristotle or Leibniz discovered, where denying them is either impossible because the argument against is self-refuting (Leibniz), or they have to start denying basic aspects of reality like causality (Aristotle). In that case, they might as well quit because it too becomes self-refuting.
If anything, I am always more concerned that people will feel utterly oppressed by the reality of an eternal existence. Since it demands action and contemplation in terms of "what to do". I can safely say that denying this is strictly ignorance, not stupidity, since the understanding of the arguments are so foundational to the human experience that people already assume them for day to day life even if they don't know it.
The desire to fit into society should never be of your concern. Would you rather be right, or think whatever everyone else thinks? Even in scripture this dichotomy is ever present through the Gospels. Understanding Christ will put you at odds with the world. Not to mention the idea that "Christians are dumb" is one of the most hilarious things someone can say, since many of the greatest minds in history were Christian, and the rest knew about God.
If you want historical evidence for Christianity, it's only one of the most researched subjects of all time. There are some good youtube channels if you don't feel like reading giant tomes.

This channel dumps tons of videos every day about various subjects, just going backwards from now on that channel is going to have almost every topic covered. Since it's Easter there have been a ton of videos about the resurrection of Christ, the historicity of the empty tomb, and other things.
