The prayer does call for serious, serious punishment on people. But I didn't call for that, God did.

Persecute them. ... Let them be put to shame and perish. ... Let his children be fatherless, and his wife a widow. ... Let his children be continually vagabonds, and beg. Let there be none to extend mercy unto him, neither let there be any to favour his fatherless children.

Let us join Paul and declare anathema upon anyone who loves not the Lord Jesus. (I Cor 16:22)
