Not remotely true. Morality is simply an exercise in relativism for the secular. For if Morality is purely a matter of ones personal decisions, then it is possible fundamentally that anything can be moral.
To argue that Morality is just as defensible in secularism as it is from a religious foundation is flat out folly. Since in the secular world, morality is what you make it, it is free to whatever the individual decides it is... not absolute fundamental basis for it exists.. it derives purely from the whim of the subjective individual... and this is a house of cards.
> in the secular world, morality is what you make it
That's astonishingly wrong. So wrong that it's clear that debatign with you would be a waste of time.
