On first point: I agreed the only power of the parliament was to reject a directive subject to codecision. That is thin.
On the second point, you misunderstand my point of view, which is surprising since it is quite common. I suspect you just do not want to understand alternative point of view on EU, but I will retry anyway.
I support democracy. Each treaty moves subjects from member state to EU, but there is still less democracy in EU institutions than in member states. At least member state MP can propose laws, something MEP still cannot do.. In my opinion, all moves we did to build EU have been regression of democracy.
In a nutshell, I refuse giving more powers to EU before it get democratic.
