Alternative take: The fact that twitter / facebook / whatever allow arbitrary, unverified posting enables large-scale misinformation that led to, among other things, Russia's manipulation the US electorate and ultimate impacting the presidential election.
This one-sided view has some good points, but for goodness sake, don't pretend that the alternative has no downsides.
Really? How many Electoral College votes did Russia's clumsy attempt at manipulation actually change? Please quantify that for us based on hard evidence.
Playing devil's advocate outside of debate club only serves to promote the devil's point of view.
State your well reasoned opinion where you have considered the facts. Or just say you are in support of this openly.
You'll need to explain how age verification fixes that.
