I have long wanted to express my views on this topic myself from
a Buddhist perspective. Perhaps when I have done more research on
it and get to understand more about buddhist teachings, I would
post it down here.
One thing that we should all understand is, based on my limited
understanding, homosexual people are very much different from what
we call sexual perverts or psychopaths.They need love and can give
love too.
I also share the same views in that hetereosexual people have
the same needs as homosexual people too, as listed by bohiruci:
1. engaging in carnal desire
2. wish for procreation, or
3. possession of opposite sex.
However I wish to add another one: Need for true love from a
life partner or any type of relationship.
In any kind of romantic relationship, emotional commitment is
very important. If homosexuals practise casual sex or adultery (if
marriage for them is legalised in SG), the consequences will be the
same as that of heterosexuals.
