I want to preface all of this by saying I do not condone throwing at another player ever. The Astros are big ole cheaters, but no one should be throwing at them.
I do think that using your words is acceptable. Players, feel free to talk as much trash as you like. Smack talk is endlessly more satisfying to me than seeing someone get hit, too. It is certainly more creative and it puts the two players on an even ground. No one has to get hurt, we all get to have fun. The Astros probably don’t like it and I don’t blame them, but, considering very few of the players involved suffered any consequences, getting their feelings hurt is probably the worst thing that would happens to them.
