We all don't like the same thing. And that is perfectly okay. That's part of what allows for all of us to be happy-the chance to be with someone we are attracted to.
The continual need by folks on Twitter and other social media to throw shade on others because of how they look is ludicrous.
Your individual standard of beauty is not held as gospel by everyone else. Sorry, but that is the basic fact. Insults only serve to make the hurler of the insult look petty and small minded.
If you come across someone who is not attractive to you, then just ignore them. Don't say anything. Just stop. Think. And realize that you cannot nor should not speak for everyone.
