Looks like this post is written by Mr. Joshi. Who is very against Buddhism. I have read his several articles earlier. Chandragupta was a Kshatriyas. All Jain and Budhist books and text support this. Only Brahmin books call him Sudra and son of a Dasi. Brahmins call him Sudra because his grand son became buddhist. Pushyamitra Sung was a Fanatic Brahmin who killed Brahdutta and then order mass murder of Buddhist monks. He started the revival of Sanatan Dharma.
