Talk to the Cubmaster of the Pack of your concerns and about moving your son to a different Den, Talk to the Unit Commissioner, and the Dictrict Commissioner, Find another Pack, --- all option in the order given.
Thanks to all for your replies!! After some reflection, I will continue with this Den, and make some inquiries into moving my son into another Den. I do value the time and commitment that the Den leader has made to Cub Scouts, and he is not imparting any negative sentiments to the young tikes ( I am there for the den meetings ). I cannot control (to a degree) the outside influences that affect my child and hope that the Scout experience will continue to enrich him and enable him to make his own (sane) choices.
It is unfortunate that some people protest this war, but they certainly do have that right.
Thanks again, it is good to have a conservative neighbor at Free Republic!!!
