Czechs
I used to know a Czech girl who was tired of telling people she wasn't Polish and that she was better!
That doesn't add up to hatred.

Slovaks
I've been working with a couple of Slovak blokes. Good people. When English fails, the Polish language can just about do the trick.
Again, no sign of anti-Polishness from them towards the Poles in the crew at work.

why the neighbours of the English are not too fond of the English? It's not just the Scots, Welsh and Irish, but also the French, the Germans
On one level, these cross-border rivalries and mutual suspiscion do exist, but when it comes to normal human interraction, these things usually dissipate. You listed 5 nationalities, from which I have had people who I count as friends and who have counted me as a friend.
Friends can come from anywhere. Foes can come from anywhere.
