He doesn’t know the meaning of liberal.
Sure he does; as in every discussion, they are moving the goalposts to sway opinions. Now only the most extreme views will be liberal, and pro-abortion, pro-”gay marriage”, pro-affirmative action will be portrayed as “centrist”.
Some of this stuff about “liberal” & “conservative” is so twisted around that I’m not sure many of us know the true meanings of the words anymore. Generally, I think most of us would look at most of today’s Democrats & call them liberals & the Republicans (not the RINOs)& call them conservatives...and that’s not a perfect description probably.
