The title strikes me as strange. “Please go vote” seems like you’re asking a favor, and then you justify it by saying “voting is rational”, which means it shouldn’t count as a favor, I should want to do it of my own accord. Unless by “rational” you mean “in keeping with the ethics of our tribe”, in which case you would just be exhorting me to follow the ethics of the tribe. But that’s a bad way to use “rational”.
EDIT: Perhaps more likely, you’re saying that voting is not a violation of the ethics of our tribe, which then justifies you asking the favor (since it would be inappropriate to ask an unethical favor).
