This is a specious line of reasoning. Here's why:
Lots of people use Python, like Python, want to keep using Python. Moreover, they want Python to improve, rather than the reverse. Different people have different ideas about what "improve" means. Guido has his ideas, and since he's the BDFL, those are the ideas most likely to influence the direction of Python's development.
However, Guido isn't the only person with ideas, nor are his ideas the only ones that should be allowed to influence the direction of Python's development. Guido himself wouldn't even be silly enough to take this position. He knows he is not the ultimate source of wisdom in the world on all matters programming related.
So when people disagree with him, suggesting that they should leave the Python community is ridiculous. Just like Guido (and the overwhelming majority of the Python community - heck, maybe even all of it), these people are trying to improve the language.
Leaving the community isn't going to improve the language. Continuing to operate actively within it just might.
For my part, I lack the time and energy to participate in many of these discussions, but anyone who knows me knows I'm not silent because I see eye to eye with Guido on every issue :) I'm extremely greatful to the people who do give so much of their own time to try to further the Python language.
Suggesting people can "like it or lump it" is a disservice to everyone.
(Sorry to single you out Peter, I know you frequently contribute great content to these discussions too, and that there are plenty of other people who respond in the way you have in this message, but I had to pick /some/ post to reply to)
