I think I'll go puke in the bushes.
You comlain about jerks and the problem with that is that you and the other people whining don't think you ever give offence.
But boy have you pushed my buttons. Your call to be saccharine and nice whilst couching that call in weasel words is pukefully hypocritical.
Why mention 'healthy atmosphere' and 'nice positive people' and then be so dishonest as to attack others and disguise your hypocricy and nastiness by using weasel words like 'negativity' or, as Kate did, 'hateful'?
If you're going to attack someone, just be plain nasty rather than trying to disguise it as being about the health of the ng.
