No. The universally revered Rabbi Yisroel Meir Kagan in his book Chafetz Chaim (1873) writes in the Laws of Evil Speech 8:5 that Judaism mandates us to hate, insult and disgrace any Jew who denies the divine origin of any part of the Pentateuch or the legal portions of the Talmud.
Are there other rabbis today who are preaching or practicing such behavior?
Yes. The Yad L'Achim agency in Israel conducts a very active program to harass Jewish Christians who are attempting to convince other Jews to convert to Christianity and this is endorsed by many respected rabbis. Jewish skeptic bloggers are no better than Christian missionaries and in fact may be worse. Rabbi Elchonon Wasserman wrote "now an evil has sprung up worse than idolatry and this is atheism".
How has the Internet created a small but tragic wave of Jewish heresy?
The Internet has made pornography easily, privately and universally available. This in turn has led to sex addictions which have then led Jews to convert to atheism. The Talmud Niddah 13b insightfully comments: Rab stated "A man who wilfully causes erection should be banned because he incites his desires upon himself". R. Ammi stated: "He is called a transgressor, because such is the art of the evil inclination: Today it incites a man to do this, tomorrow it incites him to that and the next day it incites him to worship idols and he proceeds to worship them." In our times, atheism has replaced idolatry. Imagine the effect it would have on society if cocaine were to be legalized, it would be cheaply and conveniently available by mail order to anyone with a credit card and furthermore people would on a weekly basis receive free sample packets of cocaine in the mail from drug companies. This is basically what the Internet has done, however regarding pornography not cocaine, something which at least from an Orthodox Jewish point of view is probably equally harmful. Every individual, family and community must cope with and battle with this new reality. I hope that my blog can make some small contribution.
Why do I occasionally use crude slang terms when criticizing Jewish heretics?
This is done to emphasize that the motives which these people have are in no way intellectual or idealistic, rather their choices are based on the most degrading, debased and disgusting impulses.
Aren't people who accuse others of something usually guilty of it themselves?
Not to my knowledge. I don't think that law enforcement officials for example are typically thieves and murderers. I don't think that child protection service workers are typically child abusers. I don't think that drug enforcement agents are typically drug addicts.
Do you advocate using violence to fight Jewish heretics?
No. I don't advocate, have never advocated and have never been guilty of doing anything illegal to fight Jewish heretics. I have however been myself victimized by Jewish heretics who have contacted my wife, my rabbi, my employer, law enforcement officials, child protection services, Google and others to make complaints. I have also received violent threats. In addition most Jewish heretic bloggers do not allow me to comment on their blogs, although I welcome their comments on my blog.
Doesn't criticizing Jewish heretics violate the blogger.com content policy concerning hate speech?
This policy seems to be interpreted very liberally by blogger.com. This blog for example has been sitting out there for years with apparently no problem from blogger.com. Apparently blogger.com does not want to become an arbitrator of political and religious beliefs.
