hi Ellie,
I think a good way of looking at it is that even though white may have a slight advantage, your chances of being white or black should be equal. So, even though it may feel like you're playing a black game everytime today if you look at your games over a month's time you should see that you've been black about 50 percent of the time and white 50 percent of the time (assuming chess.com has the correct game selection processes in place). This then shouldn't really be an incentive for us to change any rules as we will play white as much as any of our opponents.
Another thing to think about is the amount of work that has gone into openings throughout the years. For any moves white make, black has just as good of a move in return. With all of the types of gambits and attacking opportunities that black can get I really do think they aren't at much of a disadvantage, if any. Especially if we consider that black gets to counter white. White gives up a lot of information by the opening they do and black can respond in return.
Actually, who gets white is already randomly decided. So, instead of choosing which color goes first, you are choosing who gets to play white. Essentially, it is the same thing.
This.
