I didn't know that Taylor spoke openly about Picture to Burn and the fact that she does not perform it anymore virtually at all.
Her statement was basically that the ways in which she expressed anger at someone, and the words she used, are not the ways she expresses herself today and the song does not reflect that growth and change.
she also stated publicly that it was her that made the changes to the lyrics to avoid the "homophobic slant", and changed the official video as well.
You can still find the original on the internet.
If this is old news, sorry about that. But the lyric had always bothered me in the past. And I am just grateful that she was strong enough to admit publicly why it was inappropriate and that she certainly does not support it now.
