Yes, I think you're overall right on your description of what is happening, but I disagree somehow with your analysis. My reading of that is that social media 'accelerate' culture, and some of it is towards hateful, violent way. It's not that we come 'back' to animal instincts, it's that some new, emergent cultures push towards violence.
To your other point, I have a friend who thinks social media and online porn drive fetishism, and that fetishism drive a lot of the new 'illiterate' political movements. I don't think I totally agree with him on the illiterate part (I mean, Renaud Camus certainly managed to read Maurras before paraphrasing him, in an objectively worse way, sure, but still), but I have trouble arguing against his other points. He also thinks that this fetishism taken too far will push people towards a death cult, and kill millions
