IMO there is the totalitarian left that wants to make everyone over in their image. At the other extreme there is the extreme right that wants a Darwinian , survival of the fittest, society. Left or right, extreme or moderate, these people are at opposite poles and sincerely believe in their convictions.
I remember seeing Charlie Rose, a card carrying liberal AFAIC, interviewing arch conservative icon, William F. Buckley. Rose asked Buckley, "You believe in social security, don't you ?" WFB's expression became sad, he responded shaking his head,"No I do not." Rose looked on with his expression changing to one of incredulity.
It is not so simple, should there be a 'nanny state' telling individuals what they can and cannot do, using the taxes of the workers to support the less fortunate ? Are the less fortunate lazy, shiftless slugs who avoid work to stay on the dole ? IME that is the way many conservatives see it.
Many liberals see it as a moral responsibility to take care of the poor, the infirm and the elderly. Some conservatives may agree but I think the general consensus among them is you make your bed and then you lie in it.
Does a women have the right to make decisions that effect her body, impacting her life dramatically ? Or is abortion a selfish choice completely ignoring the possibility of the life that would have been ? Is there a more divisive issue between the parties ? I don't think so.
I can sympathize with both points of view. Both sides seem to speak in absolutes in black or white with no shades of gray. Extremists on both ends of the spectrum can be ruthless and will resort to cheating and lying to further their causes. The end justifying the means.
Now add to that the corruption that the love of money brings to the system. That may affect an individual be they far left, far right or anywhere in between. Seems to me it is the human condition and the pendulum swings one way, than the other. It sometimes ends in the middle and that leaves both sides dissatisfied. Sixty two years of life have given me to understand what my grandfather meant fifty years ago when he told me to believe half of what you see and nothing that you read.
