I don't know a single Czech that uses it. It's always been an option and the word itself is quite old. Czechs also have a few regions and it seems to not include all of them. Eg. Svozil is from Brno and that is Morava. While Jiricek is from Plsen which is Bohemia (Czech). Agree about the Slovak part in the past, that was unfair to them. They got the short stick a few times but they did get beautiful mountains! Starting them in the C division was brutal though. Watching the retired Stastny's beating the shit out of the C division to make the Olympics was so wrong. Then they got to the Olympics but couldn't play all their players in important games because of loopholes and such.
The Chechnya thing is funny because they felt 'Republic' made them sound like a third world country yet now Rey and Gord are calling us Chechnya by accident. Jeff ONeail called us Chechnians last night. In fact, I hope the TSN guys keep butchering our name till the government changes it back.lol
As a weird note I got a brand new soccer jersey from Santa and it says Czech Republic too.haha
I think, in the last 5 years, society has really come around to making sure everyone says names properly. I'm all for it but this isn't that. Please call us Czechs! Not a single Czech will be offended. Not even the most 'woke' amongst us. Our 'Karens' won't even be upset.haha
