"You have taken a song that inspired and lead women out of subservience into a position of greater power."

Subservience? I hate to point out but the women's rights movement took place in the late 19th/early 20th century, some 50 years before Helen Reddy (the writer and artist of the song in question) was even born.

Female subservience was over LONG before this song became a hit and feminist empowerment was already well underway.

If you are so shallow you'd boycott a fast food chain over a commercial and try and pin it on anti-feminist sentiment, gives the impression of being incredibly transparent and faux.
