The term red herring

Is this common knowledge?  Because I have always thought it was, but I used it tonight and DH and MIL both looked at me like I had 4 dragon heads.

I learned it in 7th or 8th grade. So, yeah.

Thank god.  They were making me feel like I was the stupid one.

yes--I vote common.

Yes, I learned it in a high school civics class when we were talking about fallacies. I think we learned a lot but all I can remember of the top of my head are red herring and slippery slope.

Another common vote. I definitely learned it in an English class somewhere along the way.
