Expressivism and non-doxastic propositional attitudes

One can fear that a certain medical procedure is wrong, one can hope that one's musical composition is beautiful, one can wish that a certain action be permissible, one can intend that one's children will make the right choices, one can be horrified that someone has committed a murder[note 1], one can promise that one will gain the contract in a morally licit way, one can rejoice that the expensive painting one has commissioned is good, etc. All of these are propositional attitudes. But the objects of propositional attitudes are propositions. Hence, that a medical procedure is wrong and that one's musical composition is beautiful (and and so on) are propositions, and expressivism is false.
