Some parts of the US, use profanity a little ...(OK..a LOT)more than most...wife had to explain to a Dr from the NE that migrated South , that telling folks that their F'ing test results were good, was NOT good around here...He used it without thinking...plus numerous other words...He didnt realize he was doing it...it was completely normal to him...
Some coaches are OK with poddy mouths...(that's just my opinion...I don't curse around ladies nor children...and don't go hard core NCO unless Im with men I know well...sorta like breaking wind...not gonna do that around just anyone neither

)
If Mom and Dad are ok with cussing like a Sailor...its their kid...But I dont have to sit there and listen...had a young boy this weekend think playing dodgeball in the stands was a good idea...about the 4th time he hit me with ball...despite my wishes of dissecting the ball...I held the ball and told him..."I think you need to find a better place to play ball"....I think his mummy and Daddy who were pulling very loudly for the opposing team while sitting contently on OUR side of the field...got the clue also...there was only a gozzilion sq feet of open grass to play on, not in the stands btw...we beat'em easily also
Some coaches look for other attributes that some aren't...
And absolutely...I do think most college coaches would be 'turned off' by that...Besides being stewards for their sport...who wants young ladies who sound like WWII Navy vets...(or antique Army NCO's:)
especially in the stands...I know I would be cautious of a Coach that used extreme profanity all the time...
I was very pleased when I saw that my kids future Coach asked the blessing at our meals and has certain set rules that aren't in the interest of 'party animals'...he shares some of the values and morals that we do...BUT...my values and morals aren't a requirement of everyone...but keep in mind...those rights end where they conflict with mine...and vice versa...
I know how he'd feel about sitting beside a f-bomb contest...
Playing Devils advocate...How interested in a school would a kid, or a parent be if a Coach stood up in the stands and yelled?..."Did you see that M9*7^%%%%6& B(*&^ catch that F)*&^%$# ball....shes F-GD stud...I got to sign her F-bomb a-word....What would you think of that school...wonder what the alumni and Ad would have to say?...
but thats just my .02...
I would love to know the feelings of a collegiate coach on here...
