Reality dictates, we each get to choose our own "hammer" to bring to the game, and it should be a hammer designed to build an environment we'd all be comfortable existing within, rather than breaking something. Football is an emotional experience, especially for those heavily invested in it.
Additional tools available, when emotions may cause inappropriate responses might be;
1. "the look": The one your Mom or Dad gave you, that precisely conveyed the message to stop whatever it was you were doing INSTANTLY, or face unpleasant consequences. (If you haven't perfected your "look", it's worth working on.
2. Unnecessary questions: You absolutely know the answer to, "What was that?", "Are you talking to me?", "Did I hear you correctly?", or your own creative version that lets the speaker know, what they said was inappropriate and provides them with an opportunity to back up, or even apologize. Of course if they're stupid enough to answer the wrong way......
3. Direct response (as privately as possible) that what was said is UNACCEPTABLE, and MUST NOT be repeated.
When all else fails, Hammers are used to drive nails, and life dictates in which situations we (are all) designated to be a hammer, or a nail. When you're the hammer, it's worthwhile to concentrate your first swing on aim, rather than force, because if necessary you can always swing again, as hard as might then be necessary.
