Unfortunately this isnt just cut and dry, like all things in life there isnt a simple black and white.
It is very difficult to learn a language and older people often have alot of trouble getting there heads around the new concepts. I have just about finished traveling europe (5weeks) and have experienced the difficulty of language. But i have also learnt ALOT while i have been here.
I am launching into a long essay about things not being clear so instead ill cut it short here.
Dont judge unless you have all the facts, and every one needs to make an effort.
Its hard to learn a language but its an effort that i would be happy to make If i were to live in another country. I would also feel ok with that country expecting me to learn it.
