You’re demanding that they give up that right, and let you profess their religious beliefs for them, in exchange for “peace”.
***Your post said nothing of the sort. And, you’re wrong about this particular item as well. That’s an oblique writing style you have, to say the least.
If they agree to restrict their postings to ecumenical threads labeled "Scientism", and implicitly accept your assesment of their religious beliefs, and give up the right to profess their own you will leave them alone. Those are your terms.
