This argument is in the same category as when people link you a 2 hour YouTube video and say "if you watch this you'll understand (unsaid: and agree with) my viewpoint!"

Which is to say, I don't think the political disputes of the United States are being driven by social media algorithms because they are exactly dividing along historic fault-lines dating back the founding of the country.

The thing about blaming social media is it excuses anyone from dealing with the content of any sides complaints or stated intentions by pretending it's not real.
