"Your pretended fear lest Error should step in, is like the man who would keep all the wine out the country lest men should be drunk. It will be found an unjust and unwise jealousy, to deprive a man of his natural liberty upon a supposition he may abuse it. When he doth abuse it, judge. If a man speak foolishly, ye suffer him gladly because ye are wise; if erroneously, the truth more appears by your conviction 'of him.' Stop such a man's mouth by sound words which cannot be gainsayed. If he speak blasphemously, or to the disturbance of the public peace, let the Civil Magistrate punish him: if truly, rejoice in the truth." -- Oliver Cromwell, 1650.

Within four years of this letter, Cromwell would essentially have to put these Presbyterian inquisitors down by force and assume guardianship of the country because these people never stop.

Coincidentally, Cromwell also held that the right to the liberty of conscience, a largely heretical view for another century, was a fundamental requirement of his Protectorate, which he had to personally safeguard against everyone.

"Is not liberty of conscience in religion a fundamental? … Liberty of conscience is a natural right; and he that would have it, ought to give it; having himself liberty to settle what he likes for the public. Every sect saith: “Oh, give me liberty!” But give him it, and to his power he will not yield it to anybody else. Where is our ingenuousness? Liberty of conscience – truly that’s a thing ought to be very reciprocal."
