OPs may be ignorant, they maybe obtuse, they may be in the wrong and they may be trolls...
but how can dozens upon dozens of swearing riddled instructions to carry out intimate acts be considered a reasonable response?
For some people MN is the first forum they frequent. It is perfectly possible to post something that is innocently ignorant yet massively outrageous to MNers. Then suddenly you are being called all the names under the sun and told to fuck yourself preferably until dead? really?
Believe me it can be a massive shock that people say things on the internet they would never say in real life. It is possible to feel very very frightened and threatened by such an onslaught.
AIBU to think if the last 5 posters have covered the 'fuck off to the far side of fuck' angle then maybe you don't need to stick the boot in too?
The best case scenario is that the person on the other end is indeed a troll....in which case why are you giving them what they want?
