No, the posts I am referring to are the ones where a poster says 'If the McCann's hadn't left Madeleine alone she wouldn't be missing' or 'It's the McCann's fault Madeleine is missing they shouldn't have left the children alone' or 'Why should we have to pay for the search for Madeleine they left her alone' etc etc
Cause and effect - it's technically true. The immediate cause is 'parents left children unattended'.
There are further underlying / root causes that you can discern by asking why until you exhaust all avenues.
Why were they left alone? Because the parents wanted a child free evening.....why?
Because they would have a better time not having to supervise children. Why?
Because the presence of toddlers is not conducive during a convivial evening of drinking and eating... Why?
etc......
Then you can do the same exercise on the decision making process for leaving the door open (allegedly).
Why did they leave the door open? Because they wanted to come and go silently (allegedly). Why?
So the children didn't wake up. Why?
So they could enjoy a convivial evening of drinking and eating with their friends. Why?
Because they're all friends and the wanted to spend quality time together....etc.
