Garth has a gay family member (his sister), and has taken as big a stance against ticket resellers as someone can. He caps prices for tickets to his shows and often does multiple shows in one visit to a city so demand and supply come closer to one another.
Garth is definitely "one of the good ones." Basically everything he does is driven by trying to make as many people happy as possible.
And it really doesn't have to be an essay. I got approved with like 8 words.
