This is so disheartening. I loved that shrine and would visit it often. Sorry to say though that it’s not a huge shock, considering Portland, Oregon.
We just visited in September. Very sad to hear this but, as you say, not that surprising. Probably someone’s Portland State Persecution 101 project.
I’ve meant to visit the Grotto, since my dtr lives down there....no,not unexpected for the hateful, small minded Portland crowd....everyone and everything needs to have protection of course, except the Christians and the whites....
