Despite memes about SJW, pandering and liberalism, people ignored the actual and disconcerting agenda:
With Jon and Dany coupling, HBO is trying to legitimise incest to the general public.
They started this in season 4, slowly coerxing us into barely accepting the Jamie/Cersei romance, complete with sympathetic "we don´t choose who we love." lines in the script.
The arrow was knocked back then, and through this season, the show has drawn the arrow of incest-accept by cheaply manipulating the audience to "ship" the pairing of our de facto protagonists, despite being extremely closely related.
Jon and Dany had sex, the arrow is shot, and our western society was the target. Critical hit. Despite it being blatant incest to a degree that´s illegal and considered abhorrent in every civilization and culture ever, it´s treated as a crowning moment and "victory" for the good guys.
Even fucking animals realize that aunts/nieces are *not* for breeding, yet HBO, D&D and GRRM will brainwash an entire generation to rethink the ideas of "free love".
This has happened before. Just wait for the excuses to start popping up on the internet, wait for other shows to slowly implement this way of thinking.
Western civilization has already abandoned so many morals. Just wait till incest is legal as long as protection is used. It will happen, and GoT set it off.
