He really doesn't know what 'fascist' and 'marxist' means. But, they sound good to his base of knuckedraggers and mouth breathers.
But, he's really talking about blacks, browns, Asians, LGBTQ+ and yes... the Jews. Just think, TFG's 'real Americans' will have to do without college and pro football, college and pro basketball, baseball, soccer, gymnastics, movies (good ones, not propaganda shit) and a whole host of other activities and jobs that all of those people perform.
MAGAts, republicans and christian religious freaks desperately want to push that button. Their fevered dreams of an all lily-white America is just around the corner! Of course, they never consider that would devastate the economy. Maybe even crush it into oblivion. But, I don't think they would care because they would no longer have any rules for them or regulations for their corporate benefactors. They are like the screaming 4 year old not getting candy or Pokemon cards at the checkout aisle at the grocery store. They want what they want, consequences be damned.
Like their mantra of 'More Choice' is always better. And with no regulations we all get to have brown water coming out of our faucets one day and green the next! Night fishing will become a new thing because all the fish will glow in the dark.
As for all those "vermin" they want to get rid of, I'm trying really hard not to imagine just what they mean.
