Sounds crazy, but many ideas held by the old, classic liberals, do not disagree with conservatives. Just consider, the old time liberals (e.g.Alan Dershowitz), were not averse to debating an issue, did believe in freedom of speech, religion etc.
Then, along came the leftists, a totally different breed of cat. ..one that believes ion freedom of speech and religion on about the same level as Joseph Stalin, Pol Pol, Fidel Castro or Kim Jung Un..
Here's a test to find out if that "friend" or relation is simply liberal, or hard core leftist !
