Is the description "narrow minded" just another cheap shot. Just one more item in the bag of political cheap tricks?

Occasionally, on Fluther and elsewhere, when things get a little heated, the description “narrow minded” gets tossed out. I really do not think it is a description of intellectual capacity. I think it is intended as an insult.

Sort of like “racist”. Once upon a time, I think that there was a legitimate observation that people out of habit and/or upbringing might render a negative judgement against others based solely on skin color.

But then it became a tool. Now, all too often, the lable “racist” is simply a cheap way to try to get people with white skin to shut the fuck up if they have a legitimate disagreement with somebody who is not white (Like in the last presidential election).

Perhaps once, “narrow minded” meant that one did not really know how to evaluate a rationale debate, or analyze data.

Has that changed? Has “narrow minded” deteriorated into just another form of political insult?
