There's a lot I want to unpack, here. I don't think you're wrong overall -- in a work environment, for example, you want to select for people who are able to take criticism in an effective, objective, and non-judgmental manner. That's a minimum bar of level-headedness you should have for people that you interact with regularly, as a general rule.
However, when you open with, "this is also incredibly exhausting", it indicates to me that either a) you find yourself surrounded with an unhealthy amount of hyper-sensitive people, or b) there might be more to the "be kind" methodology that you have yet to internalize. I carried around this attitude for most of my life, and just recently am I coming to understand that truly internalizing kindness, the way the OP describes, is not "exhausting" in any way, shape, or form (unless you have kids. Children break this rule in half).
Another thing that sticks out is "if you're fighting for your living". I agree that, if you're truly fighting for your living, kindness and compassion should take a backseat to climbing Maslow's hierarchy to the point of comfortable reflection. Given that your english seems to be good and you're posting highly articulate opinions on an Internet forum, I'd be very surprised if your line of work forced you to reject kindness as part of your job, and I urge you to consider a new line of work if at all possible.
