I suggest you don’t just leave the comment and wait. I don’t think it’s one of the best things to do. This comment can easily go viral and affect your brand before you know it. It will be too late then.
If you have already replied to this person in a polite manner, explained to him/her why they are wrong and they still say ugly things, then usually there’s no more forgiving and/or convincing.
I say it’s ok to delete the comment if you’ve been through all this and they still can’t understand. There’s a distinction between “negative” and “unacceptable” posts. Ideally you should have made it clear in your “about” section that extreme comments will be deleted. If you haven’t done this, you can still do it now.
But if this is really an “unacceptable” comment, I suggest you go ahead and delete it. You ‘ve already done all that can be done.
Hope this helps.
