Three points.
A: "our" generation (if your refering to those who are on this forum) is comprised of two (and soon to be 3) separate and distinct generations. GenX (born 1960-1980) ME generation: AKA GenY (1980-2000) and soon there will be the "next gen" which has not clearly been identified yet and its placeholder is "GenZ"
B: If your referring to Me Gen, I think your "ism" is already clearly established. GenY as a whole is incredibly intolerant of all religion with unimaginable intolerance toward Christianity first, and Islam second. That is what your going to be bitching about when your old and senile.
C: Isms are not going to go away and to think that "Someday in the future all this is going to be a bad memory" is just plain ignorant. Part of these intolerances develop not from actual hatred of what is not being tolerated nearly as much as it is a rejection of what prior generations accepted so the younger generation can pretend its being tolerant as it doesnt realize its just a cog in a much larger cycle. Plus as world events occur, new hatreds will emerge. Just like I look at GenY and see them being especially hateful toward Islam and Arabs. A major part of this stems from the western Worlds view on the events of the gulf wars and 9/11. However those not as effected by it really dont have as much in born dislike of Arabs, buuut, being closer to vietnam and the ass end of WW2 in some cases, the are MUUUUUUCH more intolerant towards Asians. Times change, but intolerance simply just evolves.
