I love the 'just because the majority on LJ like Jack/Ianto, that doesn't mean that everyone does'. I get to use words like 'statistically representative' and 'logical fallacy'.

As in, it is a logical fallacy to state that the high proportion of Jack/Ianto fans amongst engaged (LJ, forum and ff.net using) Torchwood fans is not likely to be statistically representative of non-engaging Torchwood fans and casual viewers.
