That's up to you but I think I'd be very concerned about my part in publishing what later went on to incite acts of hatred. I believe Matilda does not promote anything like that, but it's only by considering it in context that I would have thought to look for it and make that determination. Caring about it doesn't automatically mean wanting to see the work censored, or worse, silently modified. But personally if I saw a problem like that I wouldn't want to be involved in the publication or promotion of it.
