He didn't say murder was "okay"--and you are correct in your summary of those that suggest Spurgeon did justify murder. They are idiots, and the most miserable kind, as they not only operate from a position of willful ignorance, but do not hesitate to libel others--including those that are their moral and intellectual betters--and do so from a hypocritical vantage.
Spurgeon called sinners to purity of faith in the God of Scripture through the Person of Jesus Christ, and rightly and Biblically conveys the seriousness of false worship and idolatry as the sins they are, and those that are biblically illiterate and totally oblivious to even the most rudimentary issues of theology are "offended" at it--and show invective and hate all while they say Spurgeon was "intolerant."
