No where, in any of the comments made by those who live daily with this illness has it been stated that there is NO control over the bowels. What has happened to our society and world when one can make a comment such as has been stated and do so in good conscience.
We are speaking of a toilet. Not a home, not a private residence, not something that is any ONE persons possession. We are speaking of a common courtesy to those who are inflicted with a very demeaning disease process. To state that they should 'wear depends' or be treated as one would an infant is preposterous.
Ignorance is something that we, as a society, provide education for. IT is a shame that there is nothing in this world anymore, to provide compassion. Not one person who has this disease or any other disease that causes these issues has asked for it. Not one child, teen, or adult has asked to be inflicted with this, and they should NOT be expected to live a life of solitude just because some IGNORANT person does not want to allow them access to a bathroom that is within their business (where this person is PAYING for things that otherwise, that person would not have a business to begin with).
There are bathrooms in all grocery stores, there are bathrooms in all restaurants, and there should be bathrooms available to those in need (due to a medical condition) anywhere that is considered a public place.
Many store owners would rather provide a toilet than have their stores cleared due to the repercussions of one with Crohns or Ulcerative colitis being denied the use of a toilet.
I would not wish these diseases on anyone, but there are days that one with such 'ignorance' needs to walk a day in the shoes of one who does battle this.

I shake my head at what the world is coming to and pray that , one day, the human race finds heart again.
