+1. ITA. QFT. etc.People mistaking being unemotional for "behaving logically" annoys me.
Unemotional =/= logical.
One thing I find happening constantly in life and often here on the forum is a misuse of the word 'logic' as well. For example I'll use prostitution. Legalizing prostitution is neither logical nor illogical on its own, imo. I personally believe it makes sense because I have no moral issues with it - for me, legalizing it is 'logical'. However, some believe that prostitution is morally wrong - for them, legalizing it would therefore be illogical.
I've just been in too many disagreements here lately where this is what's going on - a difference of personal opinion/belief/set of values, and yet one or both parties assume that only they are being logical. Of course, they are (as in the above example) - but it's possible the other person is, too!
(and no, I'm not talking about formal logic/philosophy 101 here)
