How long did he spend in prison (put there by communists)?
About 6 years althogether.
How long was JK imprisoned by communists?
Not even a day.
That is why Kaczyński hates all ex opposition members who were better anticommunists than him. Andn he`s making up legends about his and his brother`s role in Solidarity. Funny.
Is that why he's so opposed to lustration?
Sth new to me.
Polish patriots despise him - he undermines Poland at every turn.
Don`t be silly. Those Polish "patriots" you are talking about are idiotic rightards. Decent people know his merits.
