I think there's a difference between making information available to people who are looking for it and pursuing people telling them things they don't want to hear. In the case of JWs looking for information about evolution tailored to their background, I still think this is an excellent idea, and well suited to a blog on the topic. Running around the forum, or the streets for that matter, telling people your views on evolution and God whether they are interested or not seems somewhat less productive.
Evolution may be a fact. At the same time no fact is immune to revision in light of further evidence, as you apparently conceded elsewhere. So we agree on this.
It may be very unlikely that evolutionary theory will be overturned in any meaningful sense. But can we rule it out? Human history is littered with ideas that were taken for granted at the time but are now discarded. There are undoubtedly things about the world which we now take for granted, and think it would be wrong to question, but people in hundreds of years will think how could we have been so stupid. The trouble is we never know what those things are. So alongside a commitment to reason and evidence we should also have some humility and resist dogmatism.
