You make it sound as signing the petition will result directly in a law with exactly that text. It is just a petition, so that some commission on the parliament takes that idea, discuss, process it, and eventually will be integrated in a law, where all that concerns will hopefully be addressed. If you want to be sure this discussion is worked with your ideas and ideology, make sure to vote correctly in the parliamentary elections. But not asking the parliament to initiate a debate, because a term in there is “poorly” defined, seems to me, not the best way of action.
