What no one is saying is that a lot of the supporters for the candidates are celebrities. If you’re letting mentally unstable (let’s face it that’s the majority of Hollywood) dictate your opinions - Maybe you shouldn’t vote.
So, you're saying that if somebody famous also happens to like the candidate you like, that's a reason not to vote? There's so much flawed logic in your statement I'm not sure where to begin.
First off, "a lot of the supporters are celebrities" - unless we somehow live in a world where everyone is famous, this makes no sense: "celebrities" would generally be a minuscule portion of the population, if "a lot" of the supporters means either a majority or a sizable minority of the supporters, you're suggesting very few people (compared to the population at large) who are _not_ celebrities, support these candidates. (And if only this small handful of the population prefer these candidates, why are you so worried about them voting?)
Second, I've not seen particular evidence to support the idea that "the majority of Hollywood" is mentally unstable - they're largely just as stable or unstable as the rest of the population, it's just that an intense spotlight and magnifying glass gets held up to their behavior - if some random guy across town from you does something slightly unusual, it doesn't make the evening news. Most people, if you examined them closely enough, do some odd things for seemingly indecipherable reasons, it just doesn't get national attention.
Third, having the same opinion as someone who is famous, does not mean that they've dictated that opinion to you. It's entirely possible that you've both arrived at the same conclusion following different paths.
Fourth, "maybe you shouldn't vote"? So, you'd prefer it if people who believed differently than you didn't exercise their right / duty to vote. Would you prefer votes only from uninformed people who rot their brains watching Fox "News"?
