I heard overwrought reductionism is the new thing.

I though I had a decent command of English language, even if I am not a native speaker, but I have no ide what is "naive structuralism" or "overwrought reductionism" in this context.

Would any of you care to elaborate? I am serious, I am not familiar much with the UK political scene so can't tie these normal sounding phrases to anything, and would honestly appreciate some help.
