How do you propose that prevention takes place if bigoted policies like "Lets encourage them to go" are in place? That will do nothing but encourage jihad because they really will feel persecuted and martyrdom will be even more attractive.
Also your comment is so thinly related to this topic/conversation that it is transparent. I wasn't asking for examples of prevention, I was asking whether he thinks prevention is course of action that should be pursued.
Clearly you just want to rant and blame them as just being evil and that's that, and are trying desperately to shoehorn it in to the conversation. The point being made is we can never prevent the radicalising of anyone if all you are going to do is radically condemn those that are doing it (taste the irony yet?) If it is investigated and/or studied, then it will be easier to identify earlier, with the possibility to intervene and prevent, people from joining the jihad in the first place.
At the absolute least it would be useful to find those who are actively radicalising people so that they can be prosecuted. Impossible to do if all you are willing to do is cower behind your computer and point the finger at the entire Muslim demographic, don't you think?
Though it's more than obvious some members are using ISIS and chums as an excuse to rant about eradicating the entire community, and race whilst they are at it.
