Yeah - you're definitely remembering wrong or you have your countries mixed up.
Croatia was actually the only (border-) EU country that allowed passage to all refugees (I'm guessing thats what you're referring to) and there was definitely no anti-muslim sentiment or any sort of call to ban all muslims.
Don't think anybody ever thought about anything like that at all in Croatia - people still remember their own armed conflict a decade or so ago.
You probably mean the countries from the Visegrad group (Czech Republic, Hungary, Poland and Slovakia) - where some parts of the government (in especially Slovakia) were proposing to only accept Catholic refugees (which is also not the same as saying they'd ban all muslims).
