Concern Troll: A concern troll visits sites of an opposing ideology and offers advice on how they could "improve" things, either in their tactical use of rhetoric, site rules, or with more philosophical consistency. A typical formulation might involve the troll's invocation of a site's espoused ideals alongside a perceived example of hypocrisy (such as contrasting "we value free speech" with the banning of a "dissenter"), and with a call for some relevant reform by the troll. This reform will frequently be burdensome or silly - the concern troll's message is: "I have some concerns about your methods. If you did these things to make your message less effective, it would be more effective.". Surprisingly, there are people who spend so much time on the Internet that this is actually a thing they worry about....
One common tactic of concern trolls is the "a plague on both your houses" approach, where the concern troll tries to convince people that both sides of the ideological divide are just as bad as each other, and so no one can think themselves "correct" but must engage in endless hedging and caveats. This preys on a willingness to debate critics and allow dissent; everyone wastes time discussing the matter and bending over backwards, so as not to appear intolerant of disagreement, all to the great amusement of the troll.

Tone Troll: A tone troll is a serious-minded person who wants only to raise the level of discussion in the dire cesspits of the New Atheist web. Or, possibly, they're a pompous blowhard who, lacking such frivolous accoutrements as an actual argument, attempts to distract attention from said deficit by complaining that their opposition uses dirty words and ought, really, to have some strict nanny figurepossibly Mary Poppinsto wash out their mouths with soap.

JC told us that some people in the debate can be a bit nasty, unpleasant or disrespectful. He tried to start a meta-debate on the issue. I was never completely persuaded he was a likely candidate to actually debate ID.
We are rightfully pissed off at the ID movement, a specific theistic movement that has co-opted teleology and asserts there is sufficient evidence (often at the microbiological level) that demonstrates the truth of the designer.. A specific movement that sows seeds of doubt into the minds of the lay public as a means to gain finances to continuing sowing seeds of doubt.
There are many legitimate reasons for scientist's enmity of ID, from accusations of scientist's conspiracies, fraud, lies, dirty tricks....ID often slanders or libels the reputation of science, while being a dirty organisation themselves.
Illumination is not the goal of ID, but confusion and the undermining of evolution (and if possible, any remotely related sciences can be undermined by guilt by association). In this, maybe JC is an ID supporter - but in seriousness I think it is a supporter of the philosophical idea of teleology and knows its limits (and knows that faith is required to jump certain hurdles in reasoning).
Maybe JC will be back one day, and maybe he'll even try and defend an ID perspective. I suspect not. Maybe he'll disown the ID Movement and be content with a philosophical argument about teleology, but I carry little hope that is the case.
