UK, Ireland / Why English do not like Polish? [417]

hiya
just a quick question i though i ask here on forum as it seems like lots of englsh people posting. so-why english people doesn't like polish - especially polish emigrants in uk. kinda weird as i didn't observe this with reference to other immigrants in uk, i'd rather prefer to avoid word hate but maybe it should be used here;

UK, Ireland / why do you shout and throw (question for english people) [30]

hiya
well,just one more question i've got as i'm polish immigrant in uk and don't quite understand;
can any english people here on forum explain strange behave of shouting and throwing anything from cars at people walking on pavement (or sitting on bench near street/road)? it happened very often to me and few other friends when we were walking evening to work. because of this we've got to take bus to avoid walking in case we are hit with plastic bottle or cup of water or whatever?

well, i'm asking due to i heard a lot about politeness and good manners of english people but reality seems to look bit different.
