1. Polarization among
politicians is normal. Political polarization in the society, where family members often don't talk to each other because of opposing political views, is very unhealthy. Most people on either side of the political divide don't read each others' media. People don't disagree, people
hate each other.
2. Of course you can. Church hierarchs in Poland are very conservative and often pro-Russian.

Tadeusz Rydzyk has been running a pro-Russian "catholic" radio station for a few decades now. The initial 10000 Swiss franks for the radio mast came from a mystic (Vassula Ryden) who keeps saying Russia will be elevated by God and will rule other nations. Russian diplomats showed up on the radio's 8th anniversary. The radio has transmitters in Ural and operates on frequencies used by the Russian army. Tadeusz Rydzyk is de facto the head of Polish Church. Rydzyk is notorious for criticizing the West.
Grzegorz Rzeczkowski has recently written a book "Katastrofa Posmoleńska", about how the plane crash in 2010 was used to sow dissent and divide. One of the major points of contention was a catholic cross illegally placed in front of the presidential palace to honor the dead. There were pilgrimages, pious crowds, angry people insulting the new president, etc.
Ordo Iuris is a para-legal branch of the Brasilian sect TFP. It successfully campaigns for strict law based on catholic orthodoxy - for example abortion punishable with jail, next up: no divorces. Attorney General Zbigniew Ziobro supports it. It has support from other politicians, like Grzegorz Braun and Krzysztof Bosak (his wife is in OI). That it's not "real" catholicism doesn't matter, because the society at large can't tell the difference. The resemblance is where their power comes from.
Also, the whole Konfederacja Targowicka was highly conservative, nationalist, catholic and pro-Russian.
