Blunderer, I think you are being somewhat unfair to carp anglers. You are correct in observing a more laddish culture beginning to attach itself to angling, but it covers the whole sport, not just carping.
The less than desirable behaviour we are witnessing on the banks is a reflection of the declining standards in society in general.
I will never understand the carp boys' obsession with a single species where weight is God, but most of them are perfectly decent blokes entitled to their pleasure.
And at the end of the day we are all anglers together, so please, don't let's get 'factional'. Lets keep our differences on a friendly banter level.
