If someone has an issue about something said somewhere else they should raise it there rather than derail this thread.
I'm still not entirely sure which campaign OP is referring to but if it was the orchestrating of a flame war on MN to justify it's boycott of M&S it didn't seem to be well thought out. MN has a huge following and the flaming just prompted many MNters to show their support by shopping at M&S. So the "boycott" wasn't successful and just promoted sales. The ASA says the rest.

Then there was the Fathers Day March supported only by about 120 protesters. This was followed with various press interviews that focused on arguments about statistics relating to the numbers of court cases and the % of the total that represented. The number of contact orders isn't the problem, the difficulty fathers' complain about is the time it takes for their case to conclude, not having enough contact and it breaking down and the argument about statistics detracted from that.
I wouldn't want our son to loose contact if he ever has children either but I don't think F4J will help that. In my experience the organisation is very good at ratcheting up grievances about courts being out to get them. That encourages fathers to go about things in the wrong way so they alienate others which often creates a self fulfilling prophecy.
