Sadly, I am skeptical of this in the end.
First though, let me say I don't support the bill by any means. What makes me skeptical though is that in 2015 Houston failed to pass an equal rights ordinance that would have further protected the LGBT community from discrimination, including allowances to use the bathroom of choice based on gender. Before it failed, a lot of talk was made about the business that Houston would lose including the Super Bowl. Citizens still voted it down though and it failed to pass.
Afterward, the NFL said they were
still committed to coming to the city. Granted, it isn't easy to just upend the Super Bowl where commitments have already been made. Plenty of money followed though with celebrities doing concerts, more hotels moving in, and businesses popping up. Houston growth stagnated for part of 2016, but is on the rise again.
So while legislation such as this is awful, it seems people have a very short memory or just outright prefer the money to be made regardless. I would have expected more boycotts and people not wanting to perform here. Even if the Super Bowl couldn't pull out due to contracts (I'm guessing that is why), surely celebs and businesses could have boycotted and put strain on both the city and the NFL, reminding them that this won't stand in the future.
Again though, I hope the current legislation doesn't pass. I am just skeptical of the claims being made as it seems many people will still just follow the money in the end regardless. The few that are willing to thoroughly boycott are few and far between.
