It’s a little more than that they are trying to change/rewrite history.
I know the history of this, Abortion on demand was NEVER accepted.
Now in some places, mind you some places it was allowed until “quickening” but on demand? NEVER.
I remind Liberals that Margaret Sanger and all she stood for was greatly admired by Der Fuhrer Adolph Hitler.
For example, Sanger wanted Blacks culled like weeds. Hitler agreed.
