Admittedly without knowing much about them, I think Jehovah's Witnesses need to stay and fight it out online. The sheer power of the medium means that if you're voice or group is not represented, people will either not know you exist, or a great deal of mis-representation will be put into circulation and will go uncriticised. Our sense of reality is largely made through the media, and that has some pretty serious issues when it comes to how we define "free thought". if everyone gets their information from the same source, it makes conformity alot easier. The sense of who is "us" and who is "them" is made on the basis of who participates on social media and what they say. it affects not only people's sense of reality but their identity as well because it becomes the seconary (and sometimes the primary) means of socialising with other people. The court of public opinion therefore casts judgement without anyone on the side of the defence, and often on knee-jerk and emotional grounds for not being "on of us" rather than more thoughtful or well-researched reasons. As time goes on, the internet will become a more powerful medium rather than less. Whether on our laptop or on our phone, it is pretty much everywhere, and even if you're not connected you'll still feels its affects in how it affects other people's views offline. This is where people get their information from and form (or re-inforce) their opinions about other people.
That said, the internet is not a medium which encourages orthodoxy, and as a "marketplace of ideas" generally re-inforces liberal traditions of free thought. it is also extremely divisive towards beliefs that are not backed up by evidence, both because of the accessability of information and the power of peer pressure to keep individuals quiet. So I can well understand why someone would want to do this, even if I disagree with it for very practical reasons.
Whilst I admit things can get pretty obnoxious at times, places like RF desperately need devout and intelligent believers with the courage of their convictions to inform the side of the debate that belongs to theists. Simply being heard is often enough to have an effect as it can cut through some of the mis-conceptions if people are in a receptive mood. The best you can hope for, is that by changing one person's mind or even better informing them, they may well go on to change another- but it is not a linear progression. Admittedly, the diversity of opinion on the internet can be overwhelming and confusing, but you have to fight it out as that is the measure of the value of your beliefs. doubt is not the enemy, but others people ignorance certianly could be.
