your question was confusing if you say that ch denial support is a matter of faith then it's like saying that the entire global warming article should be tagged as pov faith subject as well not just the denial article you realize of course that this is not something feasible although i personally doubt man made global warming the subject has nothing to do with faith it's about facts data and interpreting analyzing understanding the data so long as the data is not false or misleading there are scientists who oppose the mainstream opinion and there are scientists who go along with the mainstream opinion in order to keep their jobs position rather than a religion issue it's more a political financial issue
