> Nazis are very fringe, they don't outnumber anybody else and can't outvote people either

Respectfully, Twitter is kind of living proof of the opposite -- clearly they can overwhelm/outvote people (and even out-spend regular folks, if you throw an $8 price tag barrier up), despite being a small number of the total population.

I don't use twitter but I sincerely doubt nazis outnumber regular users on twitter and I don't think you have real data to back up that claim. Remember, ragebait works by finding the most egregious instances of things and misrepresenting them as typical occurrences.

A single person can outvote other people. It's called sockpuppeting.
