The thing is the conversation isn't that hard to understand.
If you're a white guy, you're not a target of the most vile shit people do online. That's just a fact.
If you want to understand how pervasive and ugly abuse and harassment is, you have to listen to vulnerable communities who have to deal with it all time.
Excluding them from the conversation because you don't want to 'believe it' is a big reason why various social platforms keep repeating the same dumb ass mistakes.
