This is a great idea, I support it!!!
Peace dove as flair

Yes. That would be great. Actually, I was already looking for a white dove but could not find one, therefore the rainbow.

Hi all,
OP has made a suggestion maybe if you support it then your fine to make a suggestion and if enough support staff may implement it

Ah, o.k., thank you very much, I was not aware of this ...
So I would add this second suggestion: That chess.com may allow also non-paying members to use a peace dove as flair!!

I‘ve sent this proposal already. When we all do this, this might speed up our wish to get a peace dove as flair icon 🕊

согласен. Русский корабль - иди нахуй
Thank you very much, much appreciated, and chapeau to you!
(Translation: "I agree. Russian ship - f... you" - with reference to an incident that allegedly happened on an island off the Ukrainian cost recently ...)

Interesting detail to the rainbow flag of chess.com, which is already offered as flair:
The rainbow flag also has been (and is) used as peace symbol, but also as an LGBT-symbol. However, while the peace flag starts with (dark) blue colours on top, and has red colours at the base, the LGBT flag has red on top, and blue (and purple) at the base.
https://en.wikipedia.org/wiki/Rainbow_flag#Peace_movement_(1961)
The chess.com flag, however, is somehow a mix of the two, starting with blue (yet leaving out dark blue), and adding purple to the base.
So I would say even if this is an option to express a desire for peace, the peace dove would be more clear ...
(Just having written this, there is the breaking news that Putin has put Russian nuclear forces on the alert ...)
Dear co-members,
please comment if you want chess.com to create a peace dove as flair, which can be optionally added to the account name.
(I have already made such a suggestion in the official channel, but I think with your support, it may be more successful ...)
Thank you very much!
Best regards

P.S. Following a hint in the comments below (that non-paying members can't use a flair), I would add this second suggestion: That chess.com may allow also non-paying members to use a peace dove as flair!!
UPDATED Saturday 5th:
Good news by @Erik from chess.com:
The peace dove as flair will come next week!!
And it will be available even for all members!!
UPDATE:
It's accomplished - the peace dove is available for all members! (There still seem to be some issues, when it is visible in games or not, but I think this will be solved ...)
Once again, a big "thank you" to chess.com staff for enabling this!!
