''mentally challenged people''
''patient with those less fortunate (mentally)''
-The language that you used made me flinch at my computer screen and wonder whether you are aware that it comes across as being patronising and damaging to the attitudes of the general public. We (as health care professionals) have a duty to advocate the equality and promote fair treatment of the human beings with which we are FORTUNATE enough to be able to work with. We should certainly not need to 'tolerate' them, or assume that they are 'mentally less fortunate'. They are simply different, and yes - perhaps they might require our assistance to enable them to achieve things that they want to do - we are doing it out of our respect for them as human beings, not out of pity or as a good deed.
I'm sure you didn't mean those things to be derogatory or harmful, but I sincerely urge you to look again at how it can come across. After all, often it is the language used and attitudes of others that are the most disabling factors to people. We of all professions should keep this in the forefront of our minds, and aim to educate those around us.
I hope you understand that I don't wish to personally attack you, just flag up a clumsy choice of words and highlight the danger that this can have.
