the lecturer is saying
you can't enjoy French poetry until you've learned a lot of French vocabulary and grammar including all its quirks and irregularities
this part sounds reasonable - you have to understand sth and then you could enjoy/appreciate that thing (like French poetry).
quite understandably some people find this off-putting my French is still terrible for example ...
this part gets wired, which conflicts with the first part, I cannot get the point what the lecturer is actually expressing.
is it that we could enjoy French poetry without mastering French? or, I don't need to enjoy French poetry?
