When someone does something inappropriate, you tell them so as politely as possible. Just like if someone's shoe is untied or has toilet paper on it, you let them know. No one needs to ask, those are the table stakes.

(I would also point out that this thread started because you were offering unsolicited advice about using social media. I could be wrong but it seems to me like you think it's appropriate to offer someone advice unsolicited if you have a perspective that's able to see through their "excuses".)

This was the closest definition to my usage I found (American Heritage #4):

    Exaggerated and unreasoning partisanship to any group or cause.

What I meant was that you were insisting your subjective viewpoint was the only one that was valid. Other viewpoints you reduced to "excuses."

I can see how it comes off condescending, and I apologize for it. There's a paternalistic element to telling someone they've done something inappropriate, and that should be reduced as much as possible, but I don't think it can stop us from saying something altogether.
