I'm a generally happy person, too. I worked a full life, doing what I really liked to do, and now I'm retired.
Why do leftists think we're all miserable? What kind of wild fantasies do they have about us on the right? And, the constant lecturing, giving us all that goodness they carry/spew from on high. We should all be proud to be lectured by the likes of @BlueHammer.
I know this is an older post, but remember Leftists are the ones who see society's rules not as keeping society liveable, but as standing in the way of what they want to do.
I found it amusing that the same one who accused me of wanting to keep women "barefoot, pregnant, and in the kitchen..." (how booringly cliche') also accused me of making 'sweeping generalizations'.
You see, the biggest problem leftists have is that they believe their own bullsh*t. When the world doesn't match their expectations based on that BS, they are unhappy. In keeping with the philosophy of 'if they can't have it,no one will' they seek to make others (their) equal--equally miserable--because their concept of equality almost always includes stripping things to the lowest common denominator.
This is why we can't have nice things.
