That's silly. Talking about such things; with friends, family, online, etc; raises awareness of it. And the more people that are aware of such things, the more likely they are to vote against it. So if you're relying on votes to change things, then discussing it helps.
i think when it comes to big picture stuff it makes sense that everyone has proportionate input. just bc you care a lot, doesnt mean you should have more say
just make your opinion, cast your vote and let other people make their own decisions. Feeling youre right and gotta go convince all the wrong people is sort of inherantly a bad selfrighteous place to come from
EDIT:
I think there is a broader sentiment that we all just have to care more and everything will get sorted out. I think recent history hasn't bore that out. People seem to care and have extremely strong emotional opinions about everything now a days.. and I don't think in the net it's brought anything positive
