The following (for the most part) are valid points and I'm staying up past my bedtime to address them, but after this I'm going to sleep!
I can see where you're coming from, but let me ask this. This person that asked me to help him to the restroom, and I've seen around the school does not have anyone with him to help him with such tasks. But where or how does it make it acceptable to ask complete strangers for such help? In a way it's a form of self entitlement. I can understand something coming where a caregiver may not have been there for a day, but to continually come to school and expect someone to always help, that's rather selfish and arrogant. If he's at a university then he is mentally capable of understanding that.
Both of you are bringing a lot of what ifs into the scenarios, that would very reasonably affect how someone ought to deal with this situation.
My original post, and the viewpoint by which I stand, is intended to address the greater question of the meaning of dignity. Frankly, I think dignity is as convoluted a term as sexual morality. It's been so corrupted by different societal norms, religious customs, and cultural traditions over centuries that most people just regurgitate some standard definition with out really thinking about what it
could be. In my humanistic worldview, dignity is defined as I said. It is the asking of help and offering of help, the overcoming of stupid societal mores and so-called "manners" (which in this case seem counter to the societal peace and pleasantness manners are supposed to foster), and doing what is right.
Now, when one complicates the situation of course the answers may change -- that is because, like anything else to do with real life, these situations don't occur in a vacuum. Every situation is different and one must consider safety and legality issues, certainly. Likewise the question of entitlement -- we don't know the exact circumstances this individual found himself in when he chose to ask for help, and until we do we have no right to judge whether or not his behavior was too assuming. But these aren't the points I'm arguing.
My point comes back to this:
No, needing help on the toilet doesn't make someone less of a person. A trained caregiver is a godsend to someone in that situation. But disabled persons don't have egos? I'd think at the end of the day, knowing you had to have a total stranger wipe your butt would be a bit of a downer to anyone.
Why should it be? I'm not talking about grieving the loss of abilities one once had -- rather the idea that not being entirely self-reliant in this way should be a knock to one's ego. Again, I find the person who can accept help with grace more dignified than the person who thinks it should be an issue.
