in answer to the original question - no I haven't suffered discrimination for being overweight because by nature I'm pretty skinny.

But there's an opposite question - Has anyone ever been regarded warmly or treated as though you must be great musically because you are thin?
my answer - not to my knowledge. I don't think being thin a great advantage. Confidence and stage presence are what matters as a performer. Packaging and presentation matter in that they feed into confidence and stage presence but anyone can present themselves well, weight is only one aspect of what you look like.

and another opposite question - Has anyone ever been regarded coldly or treated as though you must be no good musically because you are thin?
my answer - yep. I've been told I ought to eat more (no ta, I've not got a massive appetite, I eat as much as I am comfortable with) and have to put up with a whole set of assumptions that 'everything's easy for you because you're thin' which frankly is rubbish and means I end up feeling I'm not getting credit for the hard work I put in, and am resented by people who in many other ways I am pretty close friends with.

My take on it - be healthy, be happy, be confident in what you can do and don't be lazy about anything, it's a waste of your talents. If people want to be small minded, they will be and you can't stop 'em. Put your effort into blowing them away with your performance and feel smug afterwards that you proved them wrong.

If you are overweight and feel discriminated against though, don't forget that plenty of other people suffer from discrimnation against problems that you don't have. Discrimination is, sadly, part of life - it's how you deal with it that counts. Don't let your appearance, fat or thin, rule your life - there is more to any performer than what they look like, and on the whole the folk world is a friendly place to be. Yes it suffers from the same pettiness as the rest of the world, but not as badly as plenty of other social circles.
