Before you go too far, shouldn't you designate which of your associates is/are permitted by your team rules to make insensitive gun jokes? Two of them already have.Are you ready to assume a larger role? You’ll only be asked once
You recently posted a photo of a guy with a gun looking into parked cars in your city and expressed alarm about it Something tells me your Dream Team gun-joking members don't the same physical characteristics as the guy you expressed alarm about. Be consistent.
Don't encourage "a larger role" without being specific about what you are encouraging,
