I have to wholly disagree with this. A meritocracy is extremely important in the software development community. (especially in Open Source). If sub-par code were accepted out of the spirit of "acceptance" and "diversity", then the project would be seriously affected (this does happen still). People wouldn't tolerate that mentality when engineering bridges or building automobiles.
If we abandon being judged on the merit of our action, what is left? Popularity? Arbitrary rule? This anti-merit philosophy is just Despotism is new clothes.
