Not Quite a Hypothetical Question
Say there's a man who comments on a few issues that involve women reasonably commonly in the media. These issues are not solely about women, and he is asked to comment because of his knowledge of other facets.
Then say that you hear that he used to beat up his wife; you don't know if he does anymore. Does it effect the way you view his comments?
For me some information I was passed on at the wedding I attended (and it was from a reasonably reliable) has meant that I will never listen to what he says again.
It's not that I don't think that a man who has been violent against women could never have valid contributions to any issue involving (although I do think a man who is currently violent against women is showing their attitude towards women). I do like to think (although I have no evidence for this hope), that violent men can change, that there is hope. But for me to believe that this change had happened (and I have no reason to believe that it happened in this case) then the person involved would have to stop hiding their violence.
