"Swastika" is the Sanskrit word for the symbol. Hakenkreuz ("hooked cross") is the German word for a visually similar symbol.

The Hindu meaning of the symbol is not offensive. It is the German association of the symbol with the Nazi party that is offensive.

This is the first time I've encountered an attempt at de-appropriating the term "swastika" from the Nazis, but it's not an unreasonable correction.
