To be fair, extremists on both sides can allow worse people to come to power. For us, it's the extreme left who wants to ignore all laws and rights, even ignoring the approval of half of our government to push their agendas through.
They're convincing the people to want a socialist/communist system because they want everything for free without working for it, Sodom-level legalization, the imprisonment of "Nazis" (as I mentioned before, it's everyone who opposes their ideologies or supports someone who does, like Trump) and more power for those in charge. Meanwhile, they've been caught getting directly involved with news and social media to restrict access to information they don't like, even if it could prevent people from dying.
