Bloody hell, some of you need to take a long hard look at your nasty attitudes.
sign, not another SN debate
As for but it was not what the thread was supposed to be about - what a stupid thing to say, the thread was about why parents would allow a child to wear headphones at the table and it was pointed out the SN might be one reason. IF the OP had wanted a debate on technology in modern society she could have phrased it that way... she didn't, she asked why parents would allow it. Completely different.
I wanted to read what people thought about the intrusion of technology into social interaction and what I got was a thread about how various forms of SN might necessitate wearing headphones or using electronic devices. That is fine, and interesting, and I learnt something (because I did read it), but it was not what the thread was supposed to be about
Frankly, I don't care what you wanted. It wasn't even you who started the thread, if you want a thread to discuss a certain aspect of something, start your own thread and word it appropriately 
FGS!! WHY is SN brought into everything?! ... This lad was most likely a spoilt brat with no manners. Just like the majority of DC who take their DS out for a meal and ignore the company they are in
^ THIS is exactly why 'SN is brought into everything' to TRY to educate people, because people are so ignorant they don't even consider the child might have SN.
You rude, ignorant people, alienate people who have children with special needs, people who need support, people who need MN more than you will ever know. Is it so hard to think before open your mouth or post - is it so hard to consider there might be a reason for something you simply see as 'spoilt brat behaviour'.
