Good deeds and sincerity

I felt offended and irritated when someone applauds a non-religious or non-Muslims who extolled supposedly Islamic virtues with words like, "even though s/he's a non-Muslim, s/he still upholds this and this". 

You think only Muslims do good meh? Everyone else is beneath you? 

Praise a good deed where it's due. From whoever, wherever, for whatever. 

If you're sincere in your praise, you wouldn't highlight anything else but only the deed done. 

Ikhlas.
