The long standing definitions of the word that don’t necessitate that you can only be proud of things you’ve personally done seem like plenty good reason to me. National pride isn’t an excuse to be an asshole or a bigot or to oppress people, but national pride has never been necessary for people to exhibit that sort of behaviour. Being proud of your origins and your roots and where you’ve come from is not inherently a bad thing if you’re mindful about it. And just because you don’t personally feel proud of your own roots, and I’m sure your reasons for feeling that way are perfectly legitimate, that doesn’t mean you have to project your personal feelings towards your own roots on other people who feel differently about theirs.
