Your best friend, your mutual, your sibling, your favorite author, your favorite actor, your favorite podcaster or thought leader or the friend of a friend you repost all the time could be an abuser. The nicest person at your favorite pub could be one. Until the victims come out you won't know.

And victims could be anyone as well. They can be all of the above, they can be someone you don't agree with or even despise for other reasons. They can be a man or woman or nonbinary, trans or cis. They are frequently not perfect. None of that means they deserve to be abused or disbelieved.
