The people I know of mostly complaining about science as a "white construct" are saying that they dislike the way that nonwhite cultures' contributions to shared knowledge haven't been properly recognized (i.e., the Mayans had a lot of mathematical knowledge and had a skilled astronomy tradition). They're arguing that right now the scientific establishment doesn't want to deal with the way in which the way real life suppresses nonwhite academics and how that affects who gets to do science -- things like biases in grant funding, hiring, etc., as well as the difficulties in managing the stresses from normalized racism in society.
What they are not arguing is that gravity isn't real because it was studied by a white dude. Except for someone in some random youtube video you managed to find. Congrats.
