The people we call "liberals" today simply write their own press releases. They select their words not based on what would be an accurate descriptor but based on how they want to be perceived. It's all about manipulating the population to go along with their agenda (i.e. propaganda). They're not even shy about it... Their "scholars" (read: ideologues) openly admit that such manipulation is not only excusable by the goodness of their goals, it's also incumbent on any "good person" to do this in order to help steer public opinion in the "right direction".
Just to name a few examples...
"Anti-racism" means racism (and anti-fascism means fascism).
"Gender-affirming care" means "mutilating and sterilizing vulnerable and confused people for profit".
"Welfare" means "we force you to hand over your money so we can redistribute it to those we deem more deserving", because who wouldn't want more welfare? (same goes for "social security")
"Diversity and inclusion" means "less white men and everyone must see things our way".
"Equity" means "discrimination based on immutable characteristics".
"Safe space" means "only those who agree with us are welcome".
"Personal truth" means "an uncontestable falsehood you refuse to stop believing in".
"Green" typically means "more harmful to the environment".
And so on... Nearly every buzzword they popularize is used to refer to pretty much the exact opposite of what the word actually means.
If you ask me it's inaccurate to view the group that today calls itself liberals as being the same group that used to fight for freedom, having since gone astray. It's actually the same close-minded group we used to call fascists/racists/intolerant/etc, they've just rebranded themselves to be more appealing. Or to put it another way: they hijacked the good reputation earned by old-school liberals to make themselves seem like the good guys. Not unlike how the modern trans movement piggybacked on the positive public image of the gay rights movement.
