No - it's not a straw-man argument. It's a response to the argument that "travellers cost us money", which you've just repeated in your latest post. My counterargument was that institutionalised spending on, for example bailing out bankers costs the taxpayer thousands of times more than that spent on travellers. If you spent time actually reading through this thread this would be clearly apparent. I do not apologise for your failure to keep up to speed with the debate.
I should also let you know, that I have no intention of trying to change your beliefs. Your failure to watch the film in the OP and properly read through the thread, and your knee-jerk and frankly prejudiced statements suggest to me that would be a poor use of my time. I do however feel compelled to defend traditional Scottish travellers in a public debate - hence this post.
Scottish travellers are transient agricultural workers and have been around for over a thousand years moving from harvest to harvest. The industrialisation of agriculture interrupted this seasonal movement although many still engage in the raspberry harvest and other rural activities. They've had to adapt and diversify into other fields such as recycling, construction and groundworks in order to maintain their way of life. They are part of Scottish national culture, identity and heritage. My belief is this heritage deserves public support in Scotland and that these people should be allowed to live their lives without intimidation, harassment and violence.
