The lack of falsification makes god a weak argument. How can you believe in something you can't explain? You can't prove it's there, you can't prove it's not there, it's nothing more then an idea and should only be considered as such. It should not be used to promote atrocities against humanity, induce terrible culture practices, and to endorse structural violence. The magnitude at which it's been taken as truth is irrational and its proprietors have only used it as a tool to do far more harm then good.
On top of that, the stagnant conservative way of thinking it promotes is insufficient, even dangerous, in a rapidly changing world that demands self-improvement and huge re-considerations in how we do things. Those who shun human improvement are insecure, toxic people who like to blame others for their own ineptitude and lack of willingness to do some dirty work. It's the worst form of a parasite.
