Already in 1990? I thought Wałęsa (& supporters) went overboard only towards his off-election...

I recall the use of that utterly disgusting rhetoric from Slovakia, Hungary, Romania and Croatia, too.

A further example of this: on 31 March 1990 (that is during the election campaign for the first free elections), the daily close to the then dominant right-wing party MDF published an article titled Fathers and Sons, listing mostly Jewish members of the liberal SzDSz who had either communist or Israel-connected ancestors. (And even that with many errors, I note.) MDF activists would later spread it as campaign pamphlet. (Years later, too late, the far-rightists would break off MDF and form MIÉP.)
