I’m going to assume you’re asking in good faith even though you could have just googled “woman killed for rejecting man” (or something similar) yourself to find that out, but here’s the top results for that query – meaning that these are absolutely not the only cases but just the top ones on the first page of the results:

• 19-year-old college student murdered after rejecting maintenance worker advances
• These 14 Women Were Brutally Attacked for Rejecting Men — Why Aren’t We Talking About It?
• Yet Another Woman Has Been Killed Seemingly for Turning Down a Man Who Asked Her Out
• Woman shot dead after rejecting man’s advances at bar
• Minnesota woman killed by co-worker in parking lot after rejecting his repeated romantic advances, police say
• Man Kills Woman Before Attempting To Kill Self After She Rejects Proposal (this isn’t a date but a proposal, but it fits the pattern anyhow)
• Woman killed because she refused to flirt with University of Alabama basketball star, victim’s mother claims
• Men Are Killing Thousands of Women a Year for Saying No (this is a general article on the phenomenon)

Naturally you can claim they’re lies, or exaggerations etc., but it really should be clear that this is a common phenomenon.

How many articles can you find to support the claim that men routinely get sexual harrassment charges for rejecting a woman’s advances? And do you think it’s comparable to getting literally murdered? And note that this is just the murders: other forms of abuse after rejection are also common
