I have my point of view, which is not necessarily to be agreed upon by others. There is a difference between an atheist and agnostic pertaining to belief in existence of god. Analogous to agnostic belief, i belief that existence of altruism is unknown to me. So, i do not belief in it, but i am not telling others not to believe in it.

Adoption of altruism is highlighted only in media primarily by UN and through Peace initiatives of Noble prize winners. I was very clear and used the word context in illustrating its application. The word limited timeline is because i have not seen the world from its inception and is limited by my age. Similarly, the word limited observation accounts for limited places i have lived till now. Evidence based reasoning implies that sample size in which altruism is practised is small enough to represent total population. Since, if i have not seen the evidence, than i would infer that it does not exist. I am unable to correlate relationship between altruism and unfortunate events such as mass genocide and ethnic cleansing at same time. I do not have evidence to support its adoption on mass (which is for whole population), since there are plenty of evidences that contradict its existence rather than supporting its presence.
