I'll keep bringing Kaczynski's father up. It'll soon be time to question the mother, too.
It is a known fact that Olejnik collabroated with Jaruzelski's martial-law regime. (Check wikipedia.) Many people that were in the PZPR for personal advantage had the decency to hand in their party cards when martial law was declared. At that time, most of the cultural community were boycotting the official media and entertainment circuit, and a vibrant udnerground culture began developing in Catholic churches. Churches provided a safe haven for uncensored lectures, concerts, exhibitions, poetry readings and other cultural events.
But bringing up KaczyĆski senior without providing even a shred of evidence is just so much empty fluff and blather. Sure, it's a free country, so we can even say Abraham Lincoln was actually a space alien. There's no law against it if someone doesn't mind making a fool of himself once again.
