My mother wanted the family to go on there once due to our continued refusal to go along with her irrational behaviour. She is convinced Kyle would have taken her side, and made me understand her point of view, and so occasionally shouts abuse down the phone at me for how I've ruined our relationship by refusing to go on.
She'd have fit in well with the other guests. That is to say, she is an extremely vulnerable woman who had an abusive childhood, grew up to take refuge in alcohol, (and was abusive herself due in significant part to alcohol) and became an alcoholic, and has various mental issues, and has tried or feigned committing suicide dozens of time (she is sometimes under care of a CPN).
What my mother needs is sectioning for months at a time, so she can dry out totally, talking therapy every day, and 24 hour monitoring from on-site psychiatrists to monitor how effective her medication is, and what its side-effects are.
A small segment on a show like Jeremy Kyle would, at very best, support her delusions that she's in the right. As she's not, relationships with the family won't be repaired; they'll be worsened. At worst, it would have made her suicidal. Again.
As yet, she has nevet been sectioned, because she doesn't pose a risk to anyone else (since I had the sense to leave home 
), and her suicide attempts are evidently attempts. But the ability to make true valid choices is a scale, not yes/no. She may "choose to ring", but she's basically operating at the level of a hormonal 14 year old most of the time.
So, yes, Jeremy Kyle is exploitive. You're watching people like my mother. Whether they voluntarily picked up the mobile phone or not.
