You shouldn't be shocked. Though I don't consider myself a liberal (I'm a centrist), they aren't the collective loggerheads you and MAGAs paint them. They have plenty of dimwitted reverse MAGAs in their ranks. Just as there are anti-MAGA Repubs. Both sides have people who think with their minds, as opposed to being led about by a party rope attached to a nose ring. People of whatever persuasion, as a whole, can't be lumped into a singular category, though some are stupid enough to brand themselves as such. Even they aren't analogous to being a row of Heinz Tomato Paste, as opposed to being a row of Hunt"s Tomato Paste. Take ole Abe Lincoln, for example. He was a Whig Party member. Even that party had factions that were pro and anti-slavery, pro and anti annexation of Texas. Liberals also have factions, so no surprise some bluntly tell the truth about Biden's performance, or suitability to be President. Lincoln became a Republican, who himself was a hodgepodge of both liberalism, communism, and nationalism.
Communism -
Abraham Lincoln was a member of the Whig Party and later a Republican. He believed that the government’s job was to do what a community of people could not do for themselves.
Conservative & Liberal -
Lincoln’s commitment to liberal precepts were not a commitment to liberalism in the abstract, but liberal freedoms bounded by a conservative national and republican order shorn of chattel slavery.
The problem with you so-called conservatives, especially the MAGA-infected, is you want to dump people (liberals and anyone who thinks differently than you) into a single pot. Humans being what they are makes the effort both futile and a lie. People are just too darn complex to fit into a rigid ideology, that's true even for religious groups of all kinds. Just look at the factions within such groups. Same with liberals, there are factions. So you shouldn't be shocked some tell the truth, desired or not, about Biden's unsuitability. But you know what? When you're hellbent on stereotyping people, it's what you do when you
insist on being both ignorant and arrogant. It's what you do. I suppose it's mandatory when you're a follower of Trump-Jesus, Lord of Lies.
