Live and let live means I do my thing, you do yours and lets not fall out.
Truth be told, it is the "live and let live" attitude that has got us into this mess. We have done it with our politics, traditions and culture, language, religion etc. We have become a "let and live" society i.e. more liberal in the last twenty to thirty years with less interference in peoples personal choices. However, I think it has gone from less interference in personal choices to "less interference in my personal behaviour " i.e. I will behave in any which way I want to. This has meant that a proportion of the population do what they want and do not want to be told that what they are doing is inconsiderate or wrong.
I think we also have become more selfish. We want to continue with our life style and want others to adapt to our change as a result of having children. It is all about ME ME ME ! what about the rights of others ?
You want more of live and let live, I personally think not.
