Over the past few months with the election and wotnot I have seen the following on MN and it aint pretty.
I have learned that
...even if you work there will be some smug cow telling you that you should work longer/harder rather than claim tax credits.
... anyone having more than one child and living on benefits is beneath contempt (despite the people in question pointing out that they had their children before redundancy etc)
...caring for a disabled child should not need DLA - after all you are just caring for your child innit. 
...that the Labour Govt made it too easy for people to live off the rest of us what pay taxes.
..that in good times you should save save save so you don't need to claim what you are entitled to. (Conveniently ignoring the fact that many work for a minimum wage).
All the above and more has been seen recently on MN - it's not pretty and paints a really nasty picture of MN.
I have to say I have seen the other side of the coin too - people who have gone out of their way to support others and I know the opinions above are a minority. However, they are becoming a sizeable minority and it's horrible. Please think about the effect of what you are saying before posting - some people live in an ivory tower and conveniently forget they are just one redundancy away from joining those they condemn.
