No. Upvote questions that are good, clear and show research effort, and downvote questions which don't. Upvote answers which are clear, actually answer the question itself rather than some related topic, and which are support with quotes or data. Downvote answers which are confusing, or don't support themselves with evidence. And don't forget to flag both questions and answers (or vote to close questions if you have 3000+ rep.)
There are tons of good answers on terrible questions. There is nothing wrong with downvoting the question and upvoting its answers.
This site isn't about being nice and polite at the expense of making the voting system meaningless.
And to be frank, someone with only 186 votes might want to vote more before lecturing others how to vote. You have 0 downvotes, you might want to start there. Can you honestly say you've never seen an unclear question, a question with no research, or an answer making bold claims without a shred of evidence?
The top voter so far this year has only voted 113 times. We could all catch up in three days!
