Whenever someone talks about the abuse they are dealing with online, inevitably there are people who tell them to grow a thick skin and/or ignore the trolls. I don’t doubt that most of these people have good intentions at heart, but this advice just isn’t useful.
It’s not useful because we already know it. Chances are, when you say this to someone, they have heard it before. Thanks to the internet, I believe that we have thicker skins than ever before. If you know someone who is opening up about the sort of abuse they receive, chances are they already have a thicker skin than you do. You are just hearing about what they are choosing to share with you, not the entirety of what they have received. They don’t need to hear “grow a thick skin.” They already have one.
