I don't often do it, but that particular tweet hit a nerve. I'm trying to help to build a friendly community, and I think that calling out unkind behavior when I see it is an important part of that. My options for discouraging the original tweeter (and his friends) are limited...

...but drawing attention to messages which we don't find acceptable or welcoming, and demonstrating that we don't, is one thing I can do.

I think you need to consider scale here. In this case, you increased the audience of this particular tweet, which would have only been visible in a reply in a thread, by a factor of several hundred at least (the tweeter having only 35 followers)
