It's just a simple fact that some people have better genetics to grow facial hair. Although people sometimes get hounded for growing less than up-to-par beards and mustaches, it's not their fault. But it is their responsibility to shave it off so no one is submitted to having to look at it. At least, that's the opinion that a lot of people on social media have toward the Bieb's bringing back his mustache. More importantly, though, his wife, Hailey Bieber, also seems to want him to shave it off, as well.
