Poetry in schools.

[dukealien]

should poetry be taught as a main stream subject in schools?

Yes, except for the "main" part.  English (or just own-language instruction) is hopelessly compromised today by ideology; getting beyond that is going to be "back to the future," getting past the all-is-politics Great Wall that went up just about 100 years ago to when literature was literature and appreciated as such.  Which applies to all of art, I suppose.  If you insist upon political analysis, the Illiad can be Greeks-vs-Asians and The Divine Comedy is about North Italian politics of the time; likewise Tennyson can be British-Imperial, Gargantua and Pantagruel... well, you get the picture.

The trick may be introducing true cultural relativity:  what did the Illiad mean to ancient Greeks (and Romans), and why did they think it was good?  Why was the Aeneid written in imitation, and is it any good? Today's faux cultural relativity is just a mask for damn-the-West reverse particularism.  Having a literature, and a poetry within it, is as universal (almost, but not quite) as having a language, that is, a culture.  And all cultures have a subset that's poetry, and a smaller subset of that which is *good* poetry.

Teach that, yeah?
