I don't see him convincing anyone with his arguments. At this point, anyone making conversation here is a good thing, I think the forum activity has been hit hard because of all the attacks on the site preventing people from accessing the forum and causing people to be less active. I certainly feel like I have been less active.
I agree on people making conversation and again, I have no problem with anti-JTFers coming in here and arguing with us, since it allows us to retort them.
But there are RARE cases, only about 3 that I can remember, where the skilfull trolls were good enough at what they did to cause long-time members to feel unwelcome, especially if these trolls post far more than the any other members and are strategically able to get on other member's good sides. Chaim knows how dangerous this can be to the movement which is why he has done the right thing in each of these situations before it got out of hand.
But again, they are VERY rare, and for every one of these skillful wolf-in-sheep's clothing trolls, there are 10 of the run-of-the-mill trolls who are easy to spot, and are nothing more than a nuisance, and are sometimes entertaining.
