I don't know about Austrian politics, but it seems that if the FPO is a threat, the best way to counter that would be to lower voter participation After all, they gained a greater share once the voter quantity increased, so it should be a fairly direct relationship.
Maybe that's why the USA has never voted for a party like this. We haven't reached 60% participation in a presidential election in decades.
If more people could be as apathetic as you, it would be a great thing for Austrian Democracy!
Love and tolerate.
