Those aren't even particularly fitting stereotypes. The common stereotype for Poles is that they're all car thieves. For Czechs... probably that they're even more drunk than us but that's just the default stereotype for everyone east of us.

(And of course both of those are just cultural memes and nothing I actually believe.)

It’s the British („Inselaffen“) the Germans compare to apes

I second this. I never heard anyone referring Czech or Polish people to apes and also never heard that Polish people are overly angry in any way compared to others.

People in most parts of Germany see themselves as two things: Firstly, as someone from their own region. Secondly, as sometime who isn't Bavarian.

Patriotic badasses. I obviously don't have to mention, that people who view themselves like that have IQs similar to their body temp.

White, blond, christian, healthy/strong, smart (glasses?), nationalist/proud of being Polish, badass winged hussars are badass and possibly also some 'empire' type sentiments regarding the former commonwealth with Lithuania?

I have some family like this in Poland and I know some Polish history, so this was a semi-educated guess based on that.

I think poles view themselves as true patriots of their country and true beacon of Catholic church on the East

How the average PiS voter views themselves.

Well we did almost elect a Schwarzenberg as president in 2013

I think most people here just view AH as a fact of history and don't have many grudges against you in the modern day. Some people tend to be a bit jealous of Austria being 'richer' than us today, but honestly I think that's a stupid thing for them to care about. I think the language difference is unfortunately quite a barrier for most Czechs to have any sort of closer relationship to/understanding of you all (this may well change with younger people speaking English obv)
