Trying to identify the motivations of an action from the perspective of the perpetrator doesn't mean that one agrees with their actions, no, but the post that I replied to implied that there exist reasons to support “these types of activities”, which does imply agreement with the actions of the perpetrator.

Edit: And also, it has to be said that trying to identify the motivations of an action from the perspective of the perpetrator far too often amounts to little more than apologetics and defence of the indefensible, empathising with the perpetrator and blaming the victim. I'm not saying it's never useful to consider, but it's not like it's an uncommon thing to do. Blaming the victim is nearly always the default in this culture.
