I don't see the people of Brownsville living adjacent to the launchpad, where they'd get blasted with the noise and exhaust of a giant rocket all the time. Even the ones "looking forward to the jobs, tourists and excitement that a spaceport would bring". Well, maybe the ones looking for the excitement.
Nor should they have to suck up exhaust and launch blasts. Neither should the animals in the park. I suppose these people think it's a good idea to put it into the park "because nobody lives there". But plenty of animals do - that's why it's a wildlife refuge.
Texas is huge. There's plenty of places in Texas, and elsewhere in the US, where the launch blasts won't have to blast any species that cares about it. We don't have to choose between launching and being humane.
