-I don't find you attractive, but don't take it personal.
-You know, you're really annoying when you do that thing, but don't take it personal.
-I have found that your personality is not compatible with mine, but don't take it personal.
-Don't take this personal, but you don't understand the rules in this game at all.
I'm sure you can come up with better (not so blunt) examples than what I just wrote.
My question is: What on earth does "Don't take it personal" mean?
Almost every time I hear it, my first thought is "you just made a statement about ME, why wouldn't I take it personal?".
I just find it a very strange thing to say. Often, people want to give a very subjective opinion about another person. But to disallow criticism, they append "don't take it personal" to the end - giving it some kind of undeserved objective feel.
-This is just how it is, or who I am. I'm just stating facts. Don't take this as if it was directed to you, even though it was.
Is it just me who finds the expression unfair? If the other person reacts, s/he is being immature because she took it personal when it was just meant to be taken as [...].
Maybe I'm confused because I'm not a native English speaker? Anyways, what do you think about this expression? Do you use it yourself? When is it okay to use it?
