What we can/must do for Unity, Peace and Harmony or can we do anything at all about these things?
Excellent and well written and as rightly pointed out the there are many aspects of life which have evolved over time which either go unnoticed by the radar of out dated frames of reference and/or old models of dealing with them.
First all those responsible or entrusted with the responsibility of bring in order, unity, harmony etc must be clear about all areas to be looked into and addressed accordingly to avoid problems and also be equally clear and transparent about what they wish to establish because in the ultimate analysis wisdom requires us to bequeath a livable planet, a lovable society and lovely infrastructures;
It is easier to sit in the comforts of a room or stand on podium and sermonize the need for such remedial actions but what is more effective would be to recognize and acknowledge problems as they are without resorting to hypocritical and diplomatic political correctness or global public opinion in the larger interest of the greater good of the planet and humanity ensuring maximum happiness for maximum number.
I think if at all human race evolved it should put in the back burner real estate venerations as nationalism, religious edicts drafted for a period in remote past conditions and instead live life in present in present context and make it livable for all humans and other species.
With technological advancement nabbing the wrong doers is not at all difficult and but dealing with them is becoming difficult due various appropriations of identity.
