Allowing users to delete their own comments in Django

I am using the delete() function from django.contrib.comments.views.moderation module. The staff-member is allowed to delete ANY comment posts, which is completely fine. However, I would also like to give registered non-staff members the privilege to delete their OWN comment posts, and their OWN only. How can I accomplish this?

If you want to mark the comment as deleted, just as django.contrib.comments.views.moderation.delete() does:

from django.contrib.auth.decorators import login_required
from django.contrib.comments.models import Comment
from django.shortcuts import get_object_or_404
from django.conf import settings
from django.contrib import comments

@login_required
def delete_own_comment(request, message_id):
    comment = get_object_or_404(comments.get_model(), pk=message_id,
            site__pk=settings.SITE_ID)
    if comment.user == request.user:
        comment.is_removed = True
        comment.save()
