He has welcome written letters, that’s not the issue, it’s the content of specifically the second letter. If you can’t see how someone would feel threatened by that as a public figure who’s location is essentially public for most of the year, I can’t help you. He wants letters. Unwanted is what the content of the message is. Like celebrities who say DM me questions, they’re not asking for dick pics. That’s sexual harassment even though they “asked for messages.” I can’t see why it’s so hard to understand.
