There's always this effect of "X says there are lots of foo, incredible amounts. But we are good people, which is why we believe that there is practically no foo."

"What, you disagree that we should kick off people who claim that we're wrong to say that there's practically no foo? Let me round you to the X's, who claim there's lots of foo, which is crazy."

(Of course, this caricature is immediately picked up by the people who actually do believe there's lots of foo, and who very much appreciate either them passing as moderates, or the moderates being counted as them.)

And, of course, the reverse. In an outrage-based social media landscape, it is impossible to be a moderate: you will be rounded off to the extremists regardless of what you actually say.
