Two black moves per white move sounds over the top. The ratio should be much lower. If it were 1.5:1 (for the sake of simplicity), black could be given extra half-moves. {Remove j'adoube to avoid confusion and extend the notation (e.g. e6.5), of course.}
Chess isn't fair - but I can fix it!

In the tournaments I organise I have the boards raised half an inch on the black side - this makes white have to play slightly up hill which evens things out especially in long end games where stamina becomes a factor.
Without Beast719 my chess.com experience would be "so much less complete..."

dont give black two moves! then he could stick a bishop out there, then on his next move take your queen even if the bishop could have been taken.

Just flip a coin after every move to determine who goes next. Sure, you might occasionally have a 4 year old beating a GM due to an unfortunate string of tosses, but at least it's fair.
How about double-round-robin tournaments (each player has White once and Black once against each other player), team matches where each team has White on the same number of boards as the other team (or-better yet-each player plays two games against the player he's paired against-once as White and once as Black), and even matches in which each player has White the same number of times

My right is broken and casted, so even playing online is frustrating. And put me on order for of those gray sets.
This is not true... I have seen people win with black thousands of times. In fact, I have seen more black wins than white. They both have an advantage: White, for going first. Black, for being able to know what their move is and plan out more strategical positions. (e.g. the Sicilian Defense).
It's no flaw
1) No would would ever expect each individual game to be fair: it's nature (like drawing strings)
2) white typically has less than 40% chance of winning, which isn't massively advantageous (although it does seem to show when its Kasaporov vs Deep Blue). Black is always highly playable.
3) Players swap between white and black so it's as fair as it can be.

Quote by Ruy Lopez, "Always place the board so that the sun shines in your opponents eyes". to be fair, you should only do this when playing Black. Or if there's money on the game. But under no other conditions. Except maybe if you're trying to impres a girl.
Our game of chess is kind of no more diffrent from a game of basketball....When team A gets the jumpball at the start and scores the first point it's no guarantee that the team will win the game after the regulation....Team B player mmay heave a90-foot shot and wins it....ra ra ra..

Every move that white gets, black gets two!?!?!?!? Black would win every game.
Really? Are you serious?

Life is unfair deal with it, chess is already as fair as it can possibly be, someone has to initiate a move, why not let it be white, that’s just the way it is
Everything else in chess is far fairer than any other game I have ever encountered, sixteen pieces each with each piece positioned with symmetrical correspondence to opponents' pieces and each piece having the same move pattern with equal power. 90 year olds can play with 10 year olds.
If anything, I am surprised chess games give the amount of actual results they do (e.g. 1-0 or 0-1), theoretically 99.99% games should be draws, with maybe 0.01% win for white as it does start first and that is at times an advantage (how can you lose to someone with the same 'army' as you? perplexing..."). Other than that chess is a very fair game - wait didn't I already say that.
Once every game, Black can demand the White makes a different move from the one he played.
