First off, as an adult I don’t need a”fact check” on something a politician says...I’m very capable of figuring it out on my own, as I’m sure you are too...
Second, free speech was never intended to only protect speech you liked, or agreed with....the idea was to protect speech you detest and cant stand...it was an agreement between citizens of a free nation that, even though there would be many times when people did not agree, it was more important to the survival of the republic, that ALL speech was permitted (with exception to inciting physical violence)...and yes, my friend, it even includes what you refer to as “brainwashing”...and it’s the freedom of speech that allows us to make the determination, for ourselves, as adults (through debate), whether we believe such speech is legit “brainwashing” or not...👍
And, boy, am I so grateful for that!
