You say ..." I think that the cultural differences among us are a part of what lends luster to an otherwise dull world". That's so true up to a point. When a small percentage of a different race/culture mix in with an existing culture it adds interest and vibrancy (exception being certain religion). But when you get too many 'foreigners' trying to be part of an established culture suddenly the opposite happens - it no longer feels vibrant and interesting. Racism seems to kick in. We're seeing the effect play out all over the Western world.

@Earthling50 -- Basically what I'm getting at, but perhaps a bit clumsily worded. There is a delicate balance and it takes effort that many are not willing to expend.

@evidentialist What do you mean by 'delicate balance' ... what would it look like? ... do you base it on percentage?

@Earthling50 -- Not a quantifiable 'thing'. It's that dancing on a tightwire between two elements of culture so as not to fall into the negative side or overly emphasize the altruistic where one could inflame rather than inform. That kind of balance.

@evidentialist your view is very Utopian and aligns with politicians who are dancing on a tightwire doing everything to be politically correct to ensure they get re-elected. On the ground however things are shifting - species mentality/reaction is emerging.

@Earthling50 -- You still don't understand what I'm saying or perhaps on not being clear enough. Whichever is the case, I am not one of the PC warriors, I just know that a sledgehammer is not the proper tool to drive a finishing nail.

@evidentialist Metaphors and nebulousity have their place but sometimes a clear explanation works best.
