Am I a global warming denier if I am sceptical about a piece of evidence, a theory or an argument presented by persons or organisations advocating action to tackle global warming? Am I a global warming denier if there are questions that I wish to pose on the subject of global warming and anthropogenic global warming?

I saw recently that the definition of a troll is a person in an internet fora who deliberately asks questions which are off-topic, provocative or the subject of previous (and by consensus settled) discussion. So I suppose even if I am not considered a global warming denier, I am by this definition a troll. This was something that bothered me at the time and still does: because the intention of troll hangs on intention, which is not verifiable in an internet context.

I am concerned that individuals such as myself who are not insensible to the safety and well-being of present and future humanity may be delegitemised and consigned to the lunatic fringe on the basis of a lack of agreement on political policy, where they can be denied a voice and participation in debate and safely ignored.
