it allows a bit more discussion to be undertaken rather than just putting, i sign, i agree, [your name] in a edm.
it also allows the house to voice their opinions on the situation as a whole. to be fair i suggested this came to be the first Motion to test the waters and see how it is responded to. it is something which I'm sure most people would agree with however its also an item for discussion, this will eventually end up going to a vote with do you agree with this motion (and the usual responses)
basically gives us a little bit more to do and more work for me which i'm sure you'll agree isn't a bad thing! I need to prove my worth to the house.
