Do what people did when ACTA was about to be signed - protest on the streets. A few tousand people on the streets of most big cities in a country speak to politicians louder than online petition signed by 1 000 000 people.
Polish politicians have learnt their lesson last year and now they know to not even try: http://rys.io/en/109
I think that by going to a street protest you show you care enough to spend significant amount of time, so you probably also care enough to go vote against that politician in next elections.
Clicking online poll is just too convenient to mean anything.
