Because they know they're spewing bullshit capitalist propaganda and they don't have any answer so they must pretend your comment was insignificant so as not to draw more attention to the fact that what they are trying to push is inconsistent, dishonest, and incoherent.

I always learned the most from my teachers after class and in private conversations. Our school system is superficial and childish. Most teachers are pretty smart, but aren't allowed to teach anything but the book.
