It still eludes me how labeling protesters as organized is supposed to discredit them. Do the people who reflexive regurgitate "FAKE PROTESTERS" every time really think there aren't enough pissed off Democrats in the country right now, in a political climate this polarized, to actively organize against the Trump administration and Congressional Republicans in such a fashion? Really, that's so unfathomable? You're saying Democratic constituents can't get their message heard without paging boogeyman Soros for extra cash and hired goons every time they want to scream at a congressman?
Besides, some of the most effective protests in history that have resulted in tremendously consequential policy achievements were extremely well organized, like the Civil Rights protests of the 60s. How does calling them "organized left wing activists" manage to dismiss the legitimacy of the grievances being aired? I would expect pissed off people to organize and get their voices heard.
