They've been attacking it for the last few years actually.
I read that this year, Dean Martin's daughter told the SJWs to all go to hell and she's going to continue to proudly perform it.
I also saw that this year there was quite a backlash on radio stations and a couple of them did a poll. Something over 90% of their listeners told them to play the song. So as usual, a few overly sensitive whiners, coupled with overly reactive businesses, are what ruins things.
The more people that stand up to the snowflakes instead of coddling them, the faster this crap will end.
