Why has this become a concern of NASCAR?
Great question. And unlike some of the other big businesses on the list fighting against states like Indiana and Arkansas whose legislators had initially tried to take a stance protecting small businesses opposed to being forced to support gay marriage, conservatives might actually win in forcing NASCAR to change its stance objecting to defense of traditional male-female marriage.
Remember the Dixie Chicks and the role of Free Republic in that. Making NASCAR back down is a winnable fight, and for similar reasons.
Picking winnable battles makes good sense and scores points by proving the other side can't just walk onto the field and win every battle they fight. NASCAR isn't Apple. Just how many gays are huge fans of NASCAR? If we can't win over race car drivers and fans, we have a bigger problem than we think.
I'm sick and tired of listening to defeatism from conservatives. We need to be taking the battle to the enemy. The gates of hell are defensive weapons. We're supposed to be playing offense, not defense, and certainly aren't supposed to be in full scale retreat.
