It’s ridiculous and dangerous. They aren’t pop stars. Support them if you agree with their policies, and criticize them when they are wrong. They are servants, not celebrities. And just in case you’re a fan of celebrities: they are monkeys who perform for our amusement. Also servants. I don’t want their political advice, and you shouldn’t want their advice, too.
If you’re a fan of politicians, you also think that the stripper actually likes you.
