An old saying, bordering on cliché, states that respect is earned, not given.
Sadly, this has become an argument of convenience for those who want to justify being disrespectful.
It’s true that respect is earned, but that leaves us with two options. We can treat people with respect until they have shown they haven’t earned it, or we can treat people without respect until they’ve proven they have.
Anyone who chooses the latter gets no respect from me.
