Why do we still use the term "progressive" to describe leftist ideologues and ideology?

They want to return to the past where taxes were crippling the economy.

They want to return to the past where murderous Islamo-Nazi thugs had not yet managed to topple the Twin Towers, attack the Pentagon, and cause the crash of another plane in a field in Pennsylvania.

They want to return to the past where racism was rampant and required laws and punishment to stamp out.

In short, they want to regress, not progress.

So from now on, in my vocabulary, they're Regressives.
