1. The Media attack hounds will take the opportunity to demonize you even more. If your fight was local, they will take it to the attention of the entire world.
2. You will lose. The PCs control the courts too. You will lose regardless of the merits of your case (and Irving's was pretty shaky).
3. People like Sabramerican and gcruse will take the fact that you lost as proof that they were right to besmirch your reputation in the first place.
Jews could be attacked with impunity. In writings, verbally and physically.
Those days are gone. Now we fight back.
In every arena, using the methods appropriate to the situation.
And guess what? On a level playing field- or, you can ask the Arabs, even when the odds against us- we win, or at least severally bloody the opponent.
The bullies who thought that it would always be free Jew hunting season are shocked.
And now they cry.
