Nobody is twisting your arm.
Signing a petition is fine. Oh look I agree with this, I will sign a petition. You want it - but how much do you want it?
You want standing and will sign an e-petition but you don't want it enough to send in a fiver. If standing is brought in, your match day ticket could be 10 quid less. Every game. So that fiver was well spent. You see, you even got something back for it.
Politicians aren't too arsed about petitions (unless it effects their position) but presented with something right in front of them they can't ignore it. So it is vital that in England, one ground showcases a standing area (English politicians cant be arsed going to Glasgow to see one there, though an expenses paid trip to Germany is more likely to happen) so this will help get a safe standing area up and running in an English stadium.
