I have heard in the national press that Polish are very homophobic.
Some Poles may be prejudiced but I don't think Poles have any phobias in regards to homosexuals. The reverse, it seems, is true.
My 2 best friends are lesbians and would love a holiday in Poland. Best to know before they book up I guess.
Best to know what? If they can grope each other in public? Unless they do that, or carry some banners, then they do not need to feel any phobias.
