1) swastikas usually rotate the opposite direction when used in a buddhist temple, at least in the west, I’ve noticed. Certainly it is useful for differentiating from the most antisemitic symbol of all time.

2) I’m not sure it’s so sad when buddhist is less of an expressive culture and more of internal reflection. That is, I don’t see peoples’ religious beliefs trampled by trying to be respectful to those who do view it as a nazi symbol.
