Using the acronym ISOM is just a standard American way of poking fun at a law that is being ignored (by some people that don't hang around this board.. I'm sure). There is no disrespect to Cuba or Cubans in using this term. To the contrary, in the true American fashion, they are being honored by having an alternate term that is used to talk about a much sought after item, while not DIRECTLY stating that they might be doing something illegal.
If anyone is from THAT country and living in THIS country, then they really should feel proud that ISOM is used as it is. If any ARE uptight about it, give them an ISOM cigar and tell them to relax.
