Yep....now we're more of a bouillibaise....distinct flavors all vying for position. The future is bleak in my view....at least if one looks at historical precedent.
I'm convinced that unless we outlaw abortion and start shagging (with procreation instead of recreation in mind)a bit more within marriage that the 3rd and 2nd world are going to engulf us on our on shores like so much kudzu on a red clay hillside.
That is a problem. The left wing radical types have convinced so many that the sinful lifestyle is the "way to go", for marriage is "tying you down". At the same time, they've helped disrespect many young women, turning them into fanatics through rabid feminism. As a result of the two, there are fewer marriages. Many nice men and women have fewer mates to chose from, and many others are just "shacking-up". Thus, the potential pool among those who are dignified is fewer and farther in between.
Overall, the problem is that the rational Christian heritage of the coutry that stated that sex should occur between marriage and between a man and a woman has been sabotaged by evil forces.
Things that used to be taboo are now mainstream and what used to be mainstream is now "just another choice". Pathetic, in my opinion.
Regarding immigration, though, our government has the ability to put a stop to this or to significantly slow it. However, I'm not counting on it coming out of them. I figure that at the rate things are going, the country will really be in the crapper by the time I retire. That is, if Christ hasn't returned by then.
