This is a really common belief, and they have never been closer to making it happen. The Christianity Death Cult has aligned with the MAGA Death Cult which wants to reduce the population to 100 million people. Together they will happily kill millions of us for their own sick agendas.
We have to stop them, obviously, but when it's over, we have to deal with both of those situations. MAGA will have to crushed, purged from government and society, prohibited from existing, and their leaders punished harshly for their crimes.
Religion is a bigger problem, but the solution starts by ending any special privileges that churches get, and treating them like the businesses they are, including taxing them heavily, and regulating their activities.
