Perhaps if you bothered to read up on the objectives of the IMTB it might help you to overcome your prejudices:

I can only assume that you've never got to know an Irish travellers. While every group of people will have some 'bad eggs' among them, my own experiences of meeting the Irish travelling community have always been positive.
In particular, when I was a 'trade plater' hitching across the country nearly every day I found that Irish travellers would always stop and give me a lift, even if it meant going well out of their way. If I was a travelling a long distance with them, I was always offered free food and drink (and, on a couple of occasions, even offered money to help me with my onward travels).
Narrow-minded people like you, Stevie (&R1G) could learn a lot about true generosity from many Irish travellers. (When was the last time
you gave a hitch-hiker a lift? I
always do, even if it means a detour of over a hundred miles. Many Irish travellers are equally generous).
