I dunno. Most countries have decent education systems to help prevent the need for self-glorification. Its just weird that your population needs to hear that about themselves. They shouldn't need to be told, as pride in your country is a feeling. It just shocks me that they still ignore the genocide of the native population, slavery and all the shitty things. It's a refusal to acknowledge their foundings and white-washing their history. The vision portrayed is a fiction.
If you look at your country and think "meh. It's okay, could be worse but could a whole heap better" and without resorting to bigoted reasons, you're doing okay. Anyone who requires blind praise about the country they were fated to be born into seems odd. Maybe it's just me. But this isn't really in keeping with the nature of this community so I'll stop now (though it is psychology so.....😃. No, I'll stop.}
