You're mis-framing the right of a stupid man to send unsolicited naked pictures of himself to a non-consenting woman without getting fired in a highly offensive way. You're wrong that stupidity is a justifiable excuse for that behavior.

"her silence [...] causing him to escalate to naked pictures"

Don't blame the victim's silence for "causing" an "escalation" to sending naked pictures. He decided to do it of his own free will, she did not "cause" him to do that by being silent.
