And this seems to be an issue specific to U.S. politics. Maybe it’s time to collectively agree that American democracy is about excluding people from politics, in detriment to the interests of the economic elites.
EDIT: while I generally agree that what the author calls "political hobbyist" can be harmful to specific causes and can even perpetuate the status quo/political inequalities, it is within their own right to engage in politics however they see fit. We have to keep in mind that not everyone can be actively engaged in political debates in the city hall, or organizing a group of like-minded people to fight for a specific cause. Excluding "political hobbyists" from the political debate just because they are not engaging in "real politics" (author's words) is straight up anti-democratic -- after all, who can define what "real politics" is.
