Your are correct. Religion taught me this. So why not let it backfire on them.
Yes, when they famously declared "there's no sex in USSR" it was because USSR was a theocracy.
Communism was a religion.
As much as science is a religion.
So, you extend the definition of a religion to "everything a lot of people support" and then declare that it needs to be "brought down". How does it work for you - you plan to ban people from agreeing on anything, and thus enshrine world peace?
