A talkie is a motion picture that has an accompanying soundtrack, allowing you to hear the actors in it talking.

lol, but I'm guessing you meant 'tankie'? Which is odd for you to bring up, because I didn't use that word at all. It seems like you might already know what a tankie is, if you're able to tell I was referring to them.

But sure, I'll take a crack at a definition for you. But only quid pro quo -- after I define 'tankie', I want you to define 'liberal', okay? That's only fair.

Tankie: A person who (at least nominally) holds leftist, communist, socialist views and thinks it's a wonderful idea to enforce those views with (among other things) actual tanks ... even against, say, unarmed protesters. While (at least nominally) economically leftist, they often hold some very right-wing conservative social views and are usually keen on enforcing those with abundant state violence as well. Always a big fan of countries like the USSR, China, and North Korea, and usually will not entertain any criticism of anything those countries have ever done. Usually considers 'the west' in general and the United States in particular to be the greatest evil the world has ever seen (calling them and them alone 'imperialist' -- a term that can never apply to anyone else), and will 'critically' (uncritically) support absolutely any country that stands in opposition to them ... even if that means supporting Islamic theocracies or kleptocratic oligarchies. Most importantly, they have very little tolerance for differing viewpoints and would eagerly silence differing viewpoints using state violence if given the opportunity.

Okay, now define 'liberal' in your own terms.
