You already maintain a hierarchy of grief. If you found that a colleague was inconsolable because they'd snapped a nail, you'd judge them and respond differently than if their parent was dead. It's also not just based on how "normal" the grief is, there are plenty of very religious people who would be very upset at a relative being gay.
The question "do we want to maintain a hierarchy of grief" is absurd, there is not one human alive who doesn't already do that on some level.
