why do people preach to others about their voting choice?
Why is one choice better than another? It's a personal fundamental right.
The important thing should be that you voted, not what you voted for.
I would never publicly state what I vote for - it's my opinion and my decision and it's no more right or wrong than your choice.
I think healthy debate is a great thing.
Etiquette is boring - beliefs and values should always be questioned (whether anyone chooses to go as public as this is another matter).
I don't care who knows who I vote for and expect to be ripped to shreds in return.
...and isn't that what the web is for? Having gnarly debates and posting reactionary comments to strangers?
