How do these people define democracy? Is democracy defined as only voting for what THEY want? If anything Parler would save democracy cause it allows people freedom of speech to decide what they actually want (At least IF its legit and not a honeypot which it could be) . Twitter is a threat to democracy cause they censor and ban people and don't let people have free exchange of ideas. (Also if they apparently don't like "echo chambers" then why didn't they speak out against twitter censoring and banning people?)
