i have not as well researched as author..(well researched doesnt always mean u are saying the right thing, you could be highly biased)..
whether ram disowned sita or now, whether he killed bali from behind or not , whether he killed someone for begin a shudra or not..the fact is that hindus have believed and accepeted this for thousands of years..which makes it true. and shows us the dangers of idolosing a person thousands of years ago without questioning.
this is the same as whether mohammed had sex with a 9 year old girl or not, whether he brutally killed people or not as told in hadiths..the fact that muslims accepted it for thousand years makes it true and again shows the dangers of idolising a person..
