No, game mechanics aren’t subject to copyright law. Game mechanics can be patented in the US, so long as they’re unique and nonobvious (to someone with ordinary skill in the field).
Monopoly and Magic: The Gathering both had patents on their mechanics, for example.
And of course, patents in Japan are a completely different animal than patents in the US.
Economically, Democratic policies favor poor and middle class people, which statistically makes up the majority of all white men. And there aren’t any policies that oppress white people or men the way that Republican policies oppress women or reduce support for all of the groups that Democratic policies help support.
In other words, unless you get off on the oppression of those groups, almost all white men are served by the Democratic party, even if they can’t find themselves on the list you shared.
“Black Lives Matter” was a response to black men and women being murdered by police at higher rates, of the news stories of those deaths being under-reported by comparison, and of the victims being blamed more than people of other races, particularly white people.
“All Lives Matter” as a response to “Black Lives Matter” missed the point. It’s “Black Lives Matter, too.” If all lives mattered, people wouldn’t have needed to protest the killings of black people in the first place.
Imagine if you were at a restaurant and everyone around you got their order but you, so you said “Hey, I need my order.” If the server responded with “Yes, everyone needs their order” and walked off, that would be about the equivalent to saying “All Lives Matter.”
So, is there a parallel between thinking that white men should be pandered to and saying “White Lives Matter?” Absolutely.
