It makes it more difficult for extremists to organize and spread their message when blocked  The ISPs are the gatekeepers of information. When the internet places no moral judgments on content and the ISPs let all information through without commentary, it lends an air of permissiveness to the beliefs put forward, that they are held by reasonable people. The internet is a great tool for education, but also one that can be used to sow misinformation and extreme rhetoric. Extremist groups have been able to use the internet to a remarkable extent in promoting their beliefs and recruiting new members. Worse still, the administrators of these extremist sites are able to choke of things like dissenting commenters, giving the illusion that their view is difficult, or even impossible to reasonably challenge. In doing so they create an echo chamber for their ideas that allows them to spread and to affect people, particularly young people susceptible to such manipulation. The best example of this activity is in the international jihadist community and its reaching out to people in the West. Young disaffected Muslims have received an introduction to militant Islamism from sites often based abroad, but also some domestically, increasing the number of believers in an extreme, militant form of that religion. [1] By denying these people a platform on the internet, ISPs are able to not only make a moral stance that is unequivocal, but also to choke off access to new members who can be saved by never seeing the negative messages.
