I think a key feature of the far right is to convince the masses to vote against their best interests.
How do they achieve that? Historically through demonization of minorities and lies/disinformation. The internet has proven to be an extremely effective method to spread mass disinformation. They have people doubting basic facts and believing blatant lies. It spans from demonizing minorities (from antisemitic conspiracies to falsely painting LGBT people as predators and completely destroying the definition of "groomer") to just lies about everything in general (including science, medicine, history, election validity, politics, etc.).
It astounds me that an elite, born into wealth, like Trump can come about and convince so many hard working poor people that he isn't an elite and is for them. Truthfully astounding beyond reason. Notice he has no solutions for improving the lives of working class people, he just has claims that immigrants are stealing jobs, social security. Meanwhile his actual policies (like giving more tax cuts to the absurdly rich) do nothing but make it harder for hard working people to make ends meet. It's so absurd.
I know that disinformation is strong in this age, but seriously, how can you fall for HIM? Come on, people.
