The discourse around Cuba is hilarious. Trust me, Cuba and Cubans don't care about if BordigasLasagnas00 denounces it or if DengXiaoBling69 supports it uncritically. It literally makes no difference. Please spend your time more productively than just twitter dot com debates.
Yeah ruthless criticism yadda yadda but that criticism has to go somewhere. Do you've a Party platform that can channel your views? Wide twitter audience to have your followers critically engage? It's usually a waste of time, so do it, but don't expect anything from it is all.
Now if you write a serious article with deep analysis that studies Cuban conditions closely or even better, publish your research in the form of a book or a similar medium, that's surely productive & worthwhile. Other than that, maybe just read one extra page instead of tweeting.
