I used to think Shaheed bhagat singh came from a Sikh family and he was influenced by Sikhism at young age but then later came under wrong socialist communist Marxist influences which made him turn atheistic.
But it turns out from what I read recently his family was actually hindu punjabi arya samajists and arya samajists were deeply opposed to Sikh rights marches and movements back before partition.
This is why I believe he is celebrated more of a hero by indian/hindustani nationalists.than shaheed udham singh and other Indian independence Sikh revolutionaries. Perhaps its time we totally got shot of bhagat singh and look at him in a different light as he contributed nothing for Sikhs or Sikh nationalism.
