Why don’t you spoil the ballot instead? Draw a dick on the page (not on the guy you hate the most as you could accidentally vote for them) or something and then put that in the ballot box? It gets counted as spoiled that way instead of lazy non-voter who didn’t vote because they are lazy.

Why would anyone listen to you if you won’t give any party your support, or vote for the 3rd/single issue party? They are looked at by the main parties and could get something added to their manifestos.
