Not that many people but they are vociferous and very active compared to the rest of us.
From Grok:
A 2021 Pew Research Center survey found that only 9% of U.S. adult social media users often post or share about political or social issues, while 70% never or rarely do so.
Up to 30% do occasionally post political content but do not do so frequently.
Combining multiple studies (they may vary in how they define political posts and activity), Grok estimates that 2-9% of the U.S. population might be considered as politically active and making much online commentary.
On the bottom line, a small group of people are very active in posting political related commentary – but that 90+% avoid it or seldom post political commentary.
