UK, Ireland / Are the Irish welcome in Poland? [24]

I'm applying to the University of Silesia to do my second year in English there and I was wondering will I get any abuse for being a foriegner? I have only started learning Polish so I won't know much Polish by then. I know it depends on the place and time and who I will encounter but is it likely that I could get attacked by Anti-Irish thugs or just people who hate foriegners in Poland?

Study / Irish student to choose between Univeristy of Lodz or Silesia. [3]

I have been given a chance to do my second year in Poland. I have to choose to apply to either Lodz or Silesia and I would appreciate any information you could offer. I'm doing a BA honours in English and although I don't know any Polish there's a woman from Katowice who is friends with my parents who has told me a few things about those two places. There's only one campus in Lodz where I can study English but in Silesia I can study it in Katowice or Sosnowiec. Any help would be very much appreciated, thanks.
