I was vegetarian for 11 years, fully plant based for 2, and I did cook meat at events with people who ate meat. No demographic is a singularity, though, and there are many veggie folk who wouldn’t, either on ethical grounds or on grounds of having no bloody clue how to cook meat properly.

I have two steam accounts, and I was not able to see anything related to a game marked private from my second account except when family sharing was enabled between the accounts. With family sharing on I could see all private games from my primary account on my secondary (including games which were not installed on the local system).

If you have family sharing on, hold off. Otherwise as far as I know it works as intended.
