We will not give a voice to thugs who think child abuse is "cultural" or worse, openly advocate child abuse as a reasonable method of punishment.

What does he mean here? Is he talking about people who advocate beating your child or punching him in the face, or does he mean those who advocate spanking as a method of discipline? If the latter, then I lose a lot of sympathy for his cause.

In any case, removing your discussion forum may or may not be a brave and principled stand, but it absolutely guarantees that you will be of no further influence on the issue.
