Well this is not always the case. The most famous stealing being the Greek marbles.
True, or the defacing of Roman statues by the Christians, but all that isn't what these people care about or consider 'colonialism'.
These people hate ancient Greek culture and would label it colonial and problematic or twist it into some disgusting 'We Wuz Greeks' version.
Their entire ideology is endless justifications and obfuscations ultimately built around 'White people bad, Brown people good.'
They envision Jewish Hollywood movies depicting mustache-twirling White men cracking whips on noble black savages' backs and forcing them to mine lead with their bleeding bare hands.
The truth is Europeans were misled by Christianity to view other people as equal brothers under Christ and had the harebrained idea that they could simply teach these people to be as civilized and righteous as themselves.
If White people were solely about conquest and stealing resources, then there would not be a single Black person left in Africa today.
Bringing this back to Tomb Raider, the notion of complaining about Lara's colonialism is supremely absurd.
Lara is literally a grave robber who does it for sport and ends up having to save the world from some ancient evil along the way.
Portraying any kind of Tomb Raider as a goody-two-shoes is retarded, and the developers of Tomb Raider understood this. You cannot have a serious archaeologist concerned with the preservation of ancient sites start a firefight next to a significant monument.
Or have them activate an ancient mechanism just to find out if it works or destroys an invaluable artifact.
Or climb around on a crumbling ancient temple, collapsing its facade in the process.
If they were concerned about making a game that shows respect for historic artifacts, they would have to create an archaeology simulator, carefully brushing away layers of dirt and cataloging it slowly to avoid destruction and ensure the artifact's precise location.
But all this talk of colonialism and stealing cultural artifacts is merely an attempt to justify 'White people bad.'
So Lara will either have to be apologetic and relinquish control to the superior trans BIPOC, or she will be impotent and the trans BIPOC will take over because xe are superior.
