Modern Society

Question

It's been mentioned here before and I know everyone is familiar with the mitzvah of "In their ways do not follow" (Bechukosayhem Lo seyleychoo) but I have some questions as to the Taam Hamitzva and the extent of its application today. A. Theaters, stadiums, and concerts - assuming the absence of all priytzus and arayos issues - is the idea of lo.. Do not witness the productions of the goyim, an issur on a specific event or production so to say - or is it broader, don't become a member of a crowd of goyim - don't be a fan in Yankee Stadium cheering with everyone else. The implications are obvious - can I watch popular media at home or a ball game on TV, can I even follow a sports team or count myself as a fan? Can I separate myself from the 'culture' and decide on a personal level, what I need is to watch football every Sunday for myself and not be a part of NFL nation? B. Dress: - Does the issur extend to modern fashion? Or does the fact that a woman wears long skirts, long sleeves, and a hair covering set them aside enough that the patterns and cuts can be Paris's latest (again assuming there is no issue of priytzus or arayos)? Does a man's kippah, peyos, and tzitzit - mark him as a Jew enough to allow him to wear jeans and a T-shirt (the iconic American look?) Or is the issur frequenting non-Jewish stores and patronizing their businesses? Do I need to buy my DG shirts at Yankles’ Hat shack – or does this represent an even greater perversion of the issur? C. Food - Is it now my obligation to frequent and support Jewish owned stores and products and avoid secular products as being under the cloak of lo.. Given the unprecedented display of Jewish owned and operated products and stores (were the quality isn't an issue.) Does going to Pathmark now become the same as entering the Coliseum and I now need to find myself shopping at Glatt Mart? At what point is it decided the I no longer need to be exploited by the next guy trying to turn a buck under the guise of lo.. i.e. Floor cleaner with a Hechsher etc... Or in reality is the issur so fundamental that it has to become a part of my life that I want to believe that I am better for using bleach that is Kosher? Or pay 10% more for the privilege of buying my groceries from a Jew? I’m sorry if this is a little long winded – I was discussing this with my wife and we were looing for some more insight.
