The Bhagavad Gita indicates the position we should take on SSMs if we are to save our civilisation

The Bhagavad Gita:

"Out of the corruption of women proceeds the corruption of races; out of the corruption of races, the loss of memory; out of the loss of memory, the loss of understanding, and out of this all evil." 

"Out of the corruption of SLUTS proceeds the corruption of races; out of the corruption of races, the loss of memory; out of the loss of memory, the loss of understanding, and out of this all evil." 

"Out of the corruption of TOLERATING SLUTS AND BASTARDS proceeds the corruption of races; out of the corruption of races, the loss of memory; out of the loss of memory, the loss of understanding, and out of this all evil."

sańkaro narakāyaiva

sańkaraḥ — such unwanted children [bastards]

TRANSLATION

An increase of unwanted population [bastards] certainly causes hellish life both for the family and for those who destroy the family tradition.
