Vote the way you want. It's your SP. Spend it as you wish. You have no obligation to upvote a lengthy reply. That's one of the beautiful things about Steemit. People can support what they want.

If @jamesc wants to support a person running for political office, he's free to do it. If he wants to support someone who doesn't believe in private property, he's free to do that as well. Right, @kafkanarchy84?
