Sorry for the confusion, JustAsking. I'm along the line of thought that its amazing that if a certain group of people want to 'wipe out' a certain group of people, they're legal, but if they want to wipe out indiscriminately, they're terrorists.
ORCA,
Now I see what you are getting at. The apparent inconsistency comes from confusing "speech" with "action", at least in terms of the US Constitution.
For example, in the US we have the Neo-Nazi party who openly produce literature and publicly demonstrate against the Jews and other groups that they hate. But let's suppose they were targeting only the Jews so as to fulfull your definition of one group targeting another group. The US Constitution guarantees them the same rights of free speech as any other individual or organization. They are free to publish literature, demonstrate peacefully, create a cable tv channel or whatever.
Now suppose they get a bit too passionate in their demonstrations and deface a synagogue. Now they have broken the law, and are subject to ordinary laws such as vandalism and probably special "hate crime" laws would also be invoked. The reason is that "actions" are not considered a form of expression, especially if they violate another law or impinge upon the rights of another. These days, their actions might also be labelled as terrorism, much as the actions of the Klu Klux Klan would have been so labelled if they were burning crosses on someones lawn these days.
The same Constitutional protection would cover a group of Islamic American Citizens who wanted to publish literature and demonstrate against US actions in the Middle East. It would be illegal to not allow them to march in a Memorial Day parade, for example, unless a good case could be made that the ensuing reaction from the bystanders might cause people to get hurt. You can bet that the ACLU would be in there getting "all lawyered up" (no sarcasm intended, I just like that phrase) if the town hall selectively and arbitrarily denied the Islamic group the right to march.
Either way, if the Islamic group, the Neo-Nazi party, or even the local Rotary Club (a benign civic organization of local businessmen) crosses the line from "speech" to certain offensive actions, their actions would be judged criminal and in some cases (and this is a new and ambiguous classification in America) they would be deemed terrorists.
