Blasphemy in Civil Law:
Blasphemy cognizable by common law is defined by Blackstone to be “denying the being or providence of God, contumelious reproaches of our Saviour Jesus Christ, profane scoffing at the Holy Scripture, or exposing it to contempt or ridicule”. The United States once had many penal statutes against blasphemy, which were declared constitutional as not subversive of the freedom of speech or liberty of the press (Am. and Eng. Ency. of Law, Vol. IV, 582). In the American Decisions (Vol. V, 335) we read that “Christianity being recognized by law therefore blasphemy against God and profane ridicule of Christ or the Holy Scripture are punishable at Common Law”, Accordingly where one uttered the following words “Jesus Christ was a bastard and his mother was a whore”, it was held to be a public offence, punishable by the common law. The defendant found guilty by the court of common pleas of the blasphemy above quoted was sentenced to imprisonment for three months and to pay a fine of five hundred dollars.

As I mentioned in an earlier post, blasphemy laws were once used here in the US.
Regarding your (weak) claim that “Judaism, by denying that Christ is God, commits Blasphemy against God.”:
This case of blasphemy, however, is a specific one, called “the blasphemy against the Holy Spirit” in Matthew 12:31. In Matthew 12:31-32, the Pharisees, having witnessed irrefutable proof that Jesus was working miracles in the power of the Holy Spirit, claimed instead that the Lord was possessed by the demon “Beelzebub” (Matthew 12:24). Now notice that in Mark 3:30 Jesus is very specific about what they did to commit “blasphemy against the Holy Spirit.”
This blasphemy has to do with someone accusing Jesus Christ of being demon-possessed instead of Spirit-filled. As a result, this particular incidence of blasphemy against the Holy Spirit cannot be duplicated today. Jesus Christ is not on earth—He is seated at the right hand of God.

Do me a favor and change your name to “Libertarian Capitalist” (you give Christianity a bad rap).
Jesus in Hell: Where His punishment is "boiling hot semen," Gittin 57a identified as Jesus in footnote to same, and in Jewish Encyclopedia under "Balaam."
Christians in Hell: In the above passage punished by "boiling hot excrement" which is the punishment for all who mock "at the words of the sages." (Talmud)
Jesus: "Committed bestiality," "corrupted the people," is "turned into hell." (Sanhedrin 105a)
Just answer the question: Is that Blasphemy, or is it not? YES, or NO??
