I hate the expression 'inappropriate'. It is particularly over-used in schools. And in more general usage it has become a euphemism for anything from 'a bit naughty' to 'absolutely fucking outrageous'. But I had to suppress a giggle (which in itself was probably inappropriate) when I heard that Cardinal O'Brien (Stonewall's 'bigot of the year) is standing down because of inappropriate behaviour towards young priests.
Given the track record of the Catholic church - predatory sexual behaviour and the mis-use of positions of authority would seem entirely 'appropriate' with that particular organisation's ethos.
