In Finland we have plenty of national “flag days” every year. I don’t see people putting up flags on their porch or anything but many has flag poles on their yard and flying a Finnish flag has no racist implications to it or anything like that. It’s a traditional thing to do and especially the elderly are pretty strict about it.
That was what the US used to be, but now flying a flag has too many negative connotations. Don’t let your nationalist nut-jobs ruin it for you too
If it doesn’t have a blue stripe, you can absolutely still fly the flag at your house. It’s when you have it on your shirt and car that it gets weird.
I make a lot of assumptions about people flying regular US flags in their yard, and I can’t really say any of them are positive. Could be a regional thing? I’m in a pretty heavily left-leaning area and the people that are that outwardly patriotic are typically far right. Not universally, but enough for the assumptions.
