Its a shame this post descended in to a dog fight about SN pupils.
Interestingly enough, we were just now swerving away from that and getting into an actual discussion, and you've very clearly dragged it right back there. Are you LOOKING for a bunfight??? 
The question was not about SN or other pupils with other difficult
challenges, it was a question about behaviour and what the reasons were for a perceived lowering of behaviourial standards.
The initial question was answered by a number of posters that inclusion of children with SNs/challenging behaviour were the cause. Some were very rightly offended as comments were disablist.
If i was a pupil today, it is quite conceviable that i would be deemed to have SN or need extra help in organisation or concentration and that i would be given some leeway for silly/stupid behaviour.
Again, we were wandering away from the discussion of SNs and now you not only drag it back into the conversation, but you clearly in this sentence equate SNs with "silly/stupid behaviour." I can only assume that you are trying your best to offend and start off another attack.
Today it seems people are using SN as an excuse for behaviour i would never have dreamt of
Again, does it not seem you are simply trying to start up the argument again?
Having SN or other challenges does not excuse said pupils from being
violent/swearing or other totally unexceptable behaviour
Wow... three pokes of offence at SNs in one post. A record? A shameless reach for a bunfight?
