There’s a “stain” on every generation of human beings. Vegans probably think our eating beef, poultry, and bacon, etc., is unconscionable. Time will tell who is right. Many folks think women terminating their pregnancies before childbirth will not be viewed favorably some time distant from now. The decimation of the Native American populations isn’t universally viewed as our finest hour. There are probably countless grievances we can hold against historical generations but I think it’s probably best just to try to learn from history and work to build a better world. The future is likely to condemn us for things we accept today which may be unimaginable in that future time. Slavery, for example didn’t start in the western hemisphere and the institution was thousands of years old. The end of slavery in America was a turning point in the millennia of things. I see that as an achievement of our Republic. At this point, I personally think the only thing I’m going to have to answer to future generations for is my fondness for prime rib, country ham, bbq chicken, savory catfish, and maybe my gas guzzling road machines. jmo.
