One year when I played coach-pitch my dad's lawn and garden shop sponsored the team. It was cool to see my dad's store on all the uniforms, so I know how the guy's two sons felt when they first got their new uniforms and saw their dad's store printed on them. I can also imagine how they feel that their lamebrain coach has made a point of objecting, to the point of covering the name. So let this be an important and early life lesson for them that liberals will prosecute a never ending crusade against anything fun and enjoyable. They are fundamentally angry, unhappy people and they want to make everyone else the same.
And yes, I'd make a point of being a thorn in his side after this. I'd be complaining to the league that the only one with the problem is this coach, so maybe he's the one who should throw in the towel. I'd also use it as a learning experience for the two sons, to know from a young age what the totalitarian nature of so-called liberalism is all about: their way or the highway, which quickly evolves into their way or the unmarked grave.
What a douchebag. Maybe he should just have his team sponsored by Tampax and get them some pink uniforms. And I bet his own son is the team's pitcher. The coach's son was always the pitcher, no matter how good or bad he was.
