Getting back to Roadtoad's OP, the thing is, we ALL LIBERALS now (wait a couple of moments for Luke T. and several others to recover).......OK, but in comparison to 100 years ago--or even 50.
Think about it. Women got the vote in the 1900's, Blacks got the equal opportunity that they had been guaranteed in the Constitution years before, Labor Unions got the right to organize, Social Security and Medicare were passed to provide some assurance for older/poorer Americans....
I mean, we can argue point/counterpoint as to how far we go one some of the above (Title IX, Affirmative Action, Closed Shops, funding shortfalls) but I would suggest that any "Conservative", that were to suggest as a political platform that Women should go back to the kitchen and stay out of politics, Blacks/minorities should know their place, Workers should be glad they have a job, and that Government should have no role in helping people when they retire--well, they probably couldn't get elected dogcatcher in Southern Mississippi today.
The goalposts move constantly people...and the past century has been to the left. The reaction seen these days are but a rear-guard action to try and hold the line where it's at rather than completely roll back the gains of the 20th Century.
Still, history does have a nasty habit of abhoring a status quo, so what the next Century brings remains to be seen.
IMHO as always
