Holy crap, there is so much wrong with that post.

Just because it's written like that doesn't make it copyrighted. What Hasteroth said - "Yes,
us. Define
us" - has no creative merit to it (i.e. it is not a creative work) and therefore cannot be copyrighted. Not to mention it's too short to be considered a creative work in the first place.

This is slightly debatable, but would likely not violate copyright, circumstances pending. If you are doing it purposely to entertain a large group of people, you may be in violation. If you are playing it for a few friends, you aren't. If you are driving down the street with your windows down, you aren't violating copyright.
It's a similar concept to having a few friends over and watching a movie you have bought with them. It's not considered a copyright violation. If you have a movie screening for your neighborhood, that's where you've probably crossed the line. (The line itself isn't clearly defined. A judge would have to decide such a detail on a fairly independent basis.)

Discussing anything cannot be in violation of copyright. It's the same reason a news station can use clips from last Sunday's football game, or clips out of a concert, etc. Critical commentary falls under fair use. Besides that, facts cannot fall under copyright. Forming an opinion about said facts also cannot violate copyright as the facts couldn't be copyrighted in the first place. For something to be copyrighted, it has to be put in a tangible medium (video, writing, audio, etc.) and it must have creative merit.
You're teacher obviously doesn't know crap about copyright if this is the kind of thing he/she is teaching you.
... yea ...
