Not sure where the OP mentioned that, but yes, there should be No conditions on the support and love for one's child. It's part of an unwritten contract one sign's into when one decides to have children.
Unconditional support doesn't mean protecting your son from failure or consequences in life. It just means you always offer an empathetic ear to help them process their struggles. It may even mean helping the face hard truths, so long as it's being done from a place of love and not disappointment.
I really do get the sense you know this, I'm saying it mostly because others seem to have misunderstood what I meant.
